Don't ban Russian energy, Gerhard Schroder tells Germany
A large fire has broken out at a Russian fuel depot on the Ukrainian border acting as a logistics base for Vladimir Putin's forces.
Emergency services said the blaze began around 2am Moscow time (11pm GMT) at the Transneft Bryansk-Druzhba facility in Bryansk, owned by the oil pipeline company Transneft.
No injuries have been reported and the cause has not yet been established.
Bryansk is a strategic administrative centre 154 km (96 miles) northeast of the Ukrainian border, and Russian officials said last week that Ukrainian helicopters had hit residential buildings and injured seven people in the area.
It comes as US Secretary of State Antony Blinken and his defence secretary pledged additional military aid to Ukraine in the first official US visit to Kyiv since the invasion, including advanced weapons, and a return of US envoys to Kyiv.
Meanwhile, the UK's Ministry of Defence said Russia has made minor advances since shifting to the Donbas, but its decision to besiege rather than attack Mariupol's Azovstal steel plant has "exhausted many Russian units and reduced their combat effectiveness".

Russia 'strikes Ukrainian oil depot and military installations'
Russia struck Ukraine's Kremenchuk oil refinery with long-range missiles and hit military installations in its former Soviet neighbour, the Russian defence ministry reported this morning.
The ministry said it hit Ukrainian military installations and the Kremenchuk oil refinery near the Dnipro River, which the governor of the Poltava region had said was destroyed earlier this month.
"High-precision long-range weapons destroyed fuel production facilities at an oil refinery on the northern outskirts of the city of Kremenchuk, as well as petroleum products storage facilities which fuelled military equipment for Ukrainian troops," the ministry said, though this has not been independently verified.
It comes as a Russian oil depot in Bryansk, near the Ukraine border and used as a logistical hub for troops, was ablaze overnight. The cause has not yet been determined.
Russian soldiers write 'Christ is risen' on Easter missiles
Russian soldiers wrote "Christ is risen" on missiles fired into Ukraine over the Orthodox Easter weekend as Vladimir Putin spoke about "neighbourly love" at a Moscow cathedral service.
At least a dozen people died in the Russian missile attacks exactly two months after Russian forces launched their invasion of Ukraine. The Kremlin has used the Russian Orthodox Church in its propaganda machine.
Over the weekend, Russian forces described missiles as "Easter eggs" being sent to Ukraine.
"The tankmen wrote 'Christ is risen' on their missiles," a Russian soldier told a chuckling woman in a phone recording released by Ukraine's SBU. "So we are having some fun in any way we can."

Ukraine 'can win the war with right equipment'
The US wants Russia "weakened" so it cannot invade again and Ukraine can win the war if it has the right equipment, Pentagon chief Lloyd Austin said Monday on returning from a trip to Kyiv.
"The first step in winning is believing that you can win. And so they believe that we can win," Austin told a group of journalists after the visit with US Secretary of State Antony Blinken.
The pair met Ukrainian president Volodymyr Zelensky, were the first high-profile US officials to visit Ukraine since the Russian invasion began on February 24.
"We believe that we can win, they can win if they have the right equipment, the right support," Austin said. "We want to see Russia weakened to the degree that it can't do the kinds of things that it has done in invading Ukraine."
Putin congratulates Macron and wishes him 'success'
Russian President Vladimir Putin congratulated French President Emmanuel Macron on his re-election and defeat of far-right candidate Marine Le Pen, the Kremlin said Monday, as tensions remain over the Ukraine conflict.
"I sincerely wish you success in your state activities, as well as good health and well-being," Putin said in a telegram to Macron, according to a statement from the Kremlin.
Mr Macron has liaised with Putin several times during the two months of conflict and attempted - unsuccessfully - to mediate between the sides at several points.
What was agreed on the US visit to Ukraine?
It was a visit mired in secrecy and only confirmed by the White House after it had taken place, but Washington's top diplomat Antony Blinken and defence secretary Lloyd Austin agreed several measures while meeting Ukraine's president Volodymyr Zelensky in Kyiv at the weekend.
US officials said the cabinet secretaries pledged new assistance worth $713 million (£560m) for Mr Zelensky's government and 15 allied, Nato and partner countries in the region that are fearful of further Russian aggression.
This includes more than $300 million (£235m) in foreign military financing for Kyiv and $165 million (£130m) in sales of non-US made ammunition, compatible with Soviet-era weapons the Ukrainians use.
Such financing is different from previous US military assistance for Ukraine. It is not a donation of drawn-down US Defence Department stockpiles, but rather cash that countries can use to purchase supplies.
US diplomats will return to Ukraine in the coming weeks, with Washington announcing a new ambassador to the country, Budget Brink, a veteran official. Staff from Kyiv's US Embassy had been relocated to Poland.
Ahead of the visit by Blinken and Austin, Ukrainian officials drew up a list of weapons urgently needed from the United States, including anti-missile systems, anti-aircraft systems, armoured vehicles and tanks.
It comes as the US and Nato allies have shown growing readiness to supply heavier equipment and more advanced weapons systems. Britain has promised to send military vehicles and is considering supplying British tanks to Poland to free up Warsaw's Russian-designed T-72s for Ukraine.

Russia 'made minor advances in Ukraine' in shift to Donbas
Russia has made "minor advances" in some areas since shifting its focus to fully occupying the Donbas, according to the UK's Ministry of Defence.
The ministry said in its latest intelligence briefing that Moscow is still "yet to achieve a significant breakthrough" and that its decision to besiege rather than attack Mariupol's Azovstal steel plant has "exhausted many Russian units and reduced their combat effectiveness".
US envoys to resume diplomatic presence in Kyiv
United States diplomats will begin a gradual return to Ukraine this week, Washington's secretary of state and defence chief have announced, in a further signal to Russia that its war is failing.
The trip by Secretary of State Antony Blinken and Defence Secretary Lloyd Austin - which the US confirmed only after the two had left Ukrainian territory - came as the invasion enters its third month, with thousands dead and millions displaced.
Washington ordered the withdrawal of its diplomats in the weeks prior to Russia's February invasion of Ukraine.
"Starting this week, members of that team will be able to do day trips instead into Ukraine," a US official said. "Ultimately, (they will) resume presence in Kyiv."
Britain and a host of European capitals are also reopening their embassies in Ukraine's capital in the coming days.
Russia 'downs two Ukrainian drones in Russia's Kursk region'

Blinken: Russia is failing in war aims and Ukraine 'succeeding'
After a secrecy-shrouded visit to Kyiv, US Secretary of State Blinken said Russia is failing in its war aims and "Ukraine is succeeding."
The trip by Blinken and Defence Secretary Lloyd Austin was the highest-level American visit to the capital since Russia invaded in late February, though Washington refused to confirm any travel plans.
They told Ukraine's president, Volodomyr Zelensky, and his advisers that the US would provide more than $300 million in foreign military financing and had approved a $165 million sale of ammunition.
"We had an opportunity to demonstrate directly our strong ongoing support for the Ukrainian government and the Ukrainian people. This was, in our judgment, an important moment to be there to have face-to-face conversations in detail," Mr Blinken told reporters Monday near the Polish-Ukrainian border.
Mr Austin said Zelensky's response to the aid was deep appreciation for what was being given but "he has the mindset that they want to win and we have the mindset that we want to help them win."
