The town is sometimes described as the gateway to the city of Donetsk, which has been occupied by Russia and its proxy forces since 2014. Taking Avdiivka - which lies close by - would allow Russia to push the front line back, making it harder for the Ukrainian forces to retake the territory. Only aircraft deployed to protect energy facilities, or those carrying top Russian or foreign officials, will be allowed to fly with special permission in the designated zones, according to the Vedomosti daily newspaper.

• Mr Navalny's team have been trying to undermine support for the war via YouTube.
• Historically, Russia and countries that are a part of Nato have not always got on.
• Ukraine's armed forces have been fighting against the Russian military for a year now, and countries around the the world have been supporting Ukraine by supplying weapons and armed vehicles, such as tanks, to defend themselves.
• As the brutal war in Ukraine continues, many people inside Russia are hearing and seeing a very different narrative, one where words such as war or invasion do not exist.
• After eight years of fighting a Russian-backed breakaway insurgency in the east of their country they are now watching it being shelled, bombed and rocketed by their giant nuclear-armed neighbour.

The ISW does note that Russia's advances might be the result of Ukrainian forces withdrawing to "more defensible positions" near Robotyne. When Ukraine retook Robotyne in August it was hoped that its forces would be able to cut the land corridor to Crimea, making Moscow's supply lines more complicated. The attack on the Slavneft-YANOS refinery caused no fire or casualties, governor Mikhail Yevrayev said.

What has been the impact of the Ukraine war on the rest of the world?

You can be horrified by what Russia has done and is doingas of course I amand, at the same time, be concerned about dehumanizing a whole group of people in response. But, at the same time, I can understand why this might seem like sophistry to Ukrainians who have lost their homes, their friends, and seen their fellow Ukrainians tortured and murdered. Mr Navalny's team have been trying to undermine support for the war via YouTube. "No-one attacked Russia, no-one needed these separations and these deaths," Mr Volkov wrote on Twitter. "It's strange to ban people for being Russian, whether or not they support Putin's regime," argues Anastasia Shevchenko, an activist who spent two years under house arrest for protesting against the Russian president. This week Lithuania - together with Latvia, Estonia and Poland - banned all Russian tourists, arguing they should not be enjoying democracy and freedom in Europe while their government attacks those very values in Ukraine.

That scenario, of a Russian military incursion into a Nato country, almost unthinkable until recently, is when Nato and Russia could indeed be at war with each other. Nato is certainly taking no chances and has put over 100 warplanes on full alert. Britain was one of the first countries to send reinforcements - to a grateful Estonia, where Kusti Salm is nevertheless realistic about what they can achieve. Despite desperate pleas from Kyiv for the West to come to its aid, Nato has categorically ruled out sending troops to Ukraine. "We need to give them weapons like Javelin anti-tank missiles, anti-aircraft missiles, ammunition and protective equipment. Every Nato nation should be helping them," he says. Resistance has already begun, with a nationwide call-up of men of fighting age and 18,000 automatic weapons being handed out to the citizens of Kyiv, in addition to the uniformed army and reserves who are already putting up stiff resistance.

Historically, Russia and countries that are a part of Nato have not always got on. Many people in Ukraine want the country to join Nato to avoid being dominated by Russia. The North Atlantic Treaty Organisation (Nato) is a military alliance of countries which includes the US and the UK. It is estimated the UK has spent 2.3bn on military assistance, making the country the second biggest military donor behind the US.

There are some prominent Russians who are willing to speak out against the invasion of Ukraine. Elena Kovalskaya, formerly the artistic director of the state-owned Meyerhold Theatre and Cultural Center, resigned from her role last week in protest. There has been a raft of sanctions imposed on Russia and on Russian citizens in the past week in response to President Putins invasion of Ukraine. Western powers are unwilling to send troops to fight in the conflict but have sought to make the Kremlins actions unsustainable with tough economic punishments.

• "This is a tripwire that would trigger the might of all Nato, including the US, UK and France."
• Western powers are unwilling to send troops to fight in the conflict but have sought to make the Kremlins actions unsustainable with tough economic punishments.
• "Iran's allies and proxies have been undeterred by the huge show of US force in the region - if anything the warships and aircraft carriers have acted as a magnet for attack.

It is this that makes the anti-war protests against the invasion of Ukraine so telling. Russia's invasion plan has not gone entirely to plan - Britain's Defence Intelligence says hundreds of Russian troops have been killed and resistance is stiff - but it is progressing. Russia's forces outnumber Ukraine's by more than three-to-one, and there are questions about the quality of Ukraine's military leadership and how long its forces can hold out. A spate of Ukraine-linked attacks on Russia's oil infrastructure have reportedly led Moscow's energy ministry to propose restricting flights over energy facilities. And what I'm really torn up about is that there are hundreds of phenomenal Russian journalists who are working so hard to tell Russians the truth about their own country. These are people who made very small salaries when they could have made much more by going over to the Kremlin side.

"The regional war in the Middle East, with its epicentre in Gaza, is unlikely to escalate into a World War. Currently it's not a flashpoint between the major world powers. "Certainly, the time we are living in is enormously dangerous. And the killing of three US troops in Jordan has increased the likelihood for the crisis in the Middle East deepening considerably. The head of the British Army said UK citizens should be "trained and equipped" to fight in a potential war with Russia, describing those living today as the "pre-war generation". Last week, Defence Secretary Grant Shapps warned the world could be engulfed by wars involving China, Russia, North Korea and Iran in the next five years, and said we are moving "from a post-war to pre-war world". The defence secretary has warned we are moving to a "pre-war world", top military brass are talking about conscription and tensions in the Middle East show no signs of abating. While dissenting voices to Putins invasion are minimised in Russia, the scale and the intensity of the feeling of support for Ukraine means that the opposition cannot be entirely silenced by the Kremlin.

It is firmly controlled by the Kremlin and pumps out relentless war propaganda. Ukrainians are said to shell their own cities, and Russian troops are presented as liberators. An authoritarian streak runs through Putins two decades in control of Russia and his government takes any opportunity it has to crush opposition and gag dissenters.

• But clashes have also been taking place around Kyiv and the Black Sea port cities of Odesa and Mariupol.
• Within weeks of the war breaking out, a scheme was launched called Homes for Ukraine, matching Ukrainians with families in the UK who were able to offer shelter and accommodation.
• "It is this disconnect of world view, combined with the willingness to use force, that makes the situation in eastern Europe so very dangerous.
• Russia's invasion plan has not gone entirely to plan - Britain's Defence Intelligence says hundreds of Russian troops have been killed and resistance is stiff - but it is progressing.

Eastern European countries, who fear they may be next in Putin's sights, are watching nervously for any Russian manoeuvres close to their borders. Kusti Salm, the permanent secretary at Estonia's Ministry of Defence, is one of those pushing for more military assistance to Ukraine. "But it might not destroy the Ukrainian government - provided it has made plans to set up a new government HQ, most likely in the western part of the country." Within weeks of the war breaking out, a scheme was launched called Homes for Ukraine, matching Ukrainians with families in the UK who were able to offer shelter and accommodation. But there was criticism that current rules and systems were too complicated and too strict. Mr Biden said that the US would be giving a new military aid package to Ukraine, worth $500m (around 415 million).
