A veteran aide of President Vladimir Putin has resigned over the Ukraine war and left Russia with no intention to return, two sources said on Wednesday, the first senior official to break with the Kremlin since Putin launched his invasion a month ago.
The Kremlin confirmed that the aide, Anatoly Chubais, had resigned of his own accord. Chubais hung up the phone when contacted by Reuters. The sources did not say where he was.
Chubais was one of the principal architects of Boris Yeltsin's economic reforms of the 1990s and was Putin's boss in the future president's first Kremlin job. He later ran big state businesses under Putin and held political jobs, lately serving as Kremlin special envoy to international organisations.
US President Joe Biden flies to Europe on Wednesday for an emergency NATO summit on Ukraine, where invading Russian troops are stalled, cities are under bombardment and the besieged port of Mariupol is in flames.
Four weeks into a war that has driven a quarter of Ukraine's 44 million people from their homes, Russia has failed to capture a single major Ukrainian city or depose the government, while Western sanctions have ostracised it from the world economy.
Russian forces have taken heavy losses, been frozen in place for at least a week on most fronts and face supply problems and fierce resistance.
They have turned to siege tactics and bombardment, causing massive destruction and many civilian deaths.
Moscow says its aim is to disarm its neighbour, and its "special military operation" is going to plan. It denies targeting civilians.
Worst hit has been Mariupol, a southern port completely surrounded by Russian forces, where hundreds of thousands of people have been sheltering since the war's early days, under constant bombardment and with food, water and heat supplies cut.
New satellite photographs from commercial firm Maxar released overnight showed massive destruction of what was once a city of 400,000 people, with columns of smoke rising from residential apartment buildings in flames.
No journalists have been able to report from inside the Ukrainian-held parts of the city for more than a week, during which time Ukrainian officials say Russia has bombed a theatre and an art school used as bomb shelters, burying hundreds of people alive. Russia denies targeting those buildings.
Biden, due to arrive in Brussels on Wednesday evening on his first foreign trip since the war began, will meet NATO and European leaders in an emergency summit at the Western military alliance's headquarters.
The leaders are expected to roll out additional sanctions against Russia on Thursday. Sources said the U.S. package would include measures targeting Russian members of parliament.
Biden will also visit Poland, which has taken in most of the more than 3.6 million refugees who have fled Ukraine and has been the main route for Western supplies of weapons to Ukraine.
In a sign of Moscow's further isolation, Poland announced it was expelling 45 Russian diplomats accused of either being undercover spies or "associated" with them. Several other eastern European countries have announced similar moves in recent days, although not on such a large scale. Russia has rejected all the accusations.
