Fears Russia could use chemical weapons grow as ground offensive slows
US President Joe Biden has warned that Russian forces might be considering using chemical or biological weapons in Ukraine, and a leading expert says that's a "plausible" theory.
"I think a chemical attack... is probably the most plausible because it's also the most deniable. And it also fits in with Russia's modus operandi in the past" Samuel Ramani from RUSI told Euronews.

Emmanuel Macron demands ceasefire in telephone call with Vladimir Putin
French President Emmanuel Macron spoke for an hour on Tuesday with Russian President Vladimir Putin, without any agreement for a ceasefire in Ukraine.
This was the eighth call between the two leaders since Russia launched an invasion of Ukraine on 24 February.
"There is currently no agreement but the President remains convinced of the need to continue his efforts" the French presidency said.
"There is no other way out than a ceasefire and Russia's good faith negotiations with Ukraine. The President of the Republic stands alongside Ukraine."
The phone call was initiated by France, and the previous call was held on Friday when Macron express his "extreme concern" about the situation in Mariupol.
On Wednesday Ukrainian President Volodymyr Zelenskyy will address French deputies and senators to ask for more help against Russia.
'They want to level it to the ground'
Authorities in the besieged city of Mariupol said Russian aircraft dropped two heavy bombs today causing "even greater destruction".
"Once again it is clear the occupiers are not interested in the city of Mariupol, they want to level it to the ground and turn it into ashes."
On Monday, the last European Union diplomat to be evacuated from the city said civilians there are being hit "blindly and indiscriminately".
Manolis Androulakis, Greece’s consul general, said "Mariupol will be on the list of cities in the world that have been completely destroyed by war".
Civilians who managed to escape told Human Rights Watch said men, women and children were sheltering in basements with little or no access to running water, power, heating, medical care, or mobile phone service since the siege began on 2 March 2.
“Mariupol residents have described a freezing hellscape riddled with dead bodies and destroyed buildings,” said Belkis Wille, senior crisis and conflict researcher at Human Rights Watch. “And these are the lucky ones who were able to escape, leaving behind thousands who are cut off from the world in the besieged city.”

Another Russian luxury yacht seized: this time, in Gibraltar
Authorities in Gibraltar have seized a luxury yacht belonging to Russian oligarch Dimitri Pumpianski.
It comes after a complaint from a creditor, and is linked to British sanctions against Russian interests.
This ship, the Axioma, was sailing under a Maltese flag, and was "the subject of a request for seizure by a large international bank to the Supreme Court of Gibraltar" the government said on Monday.
Gibraltar is a small British enclave on the southern tip of Spain.
Gibraltar allowed the Axioma to enter port - a move which otherwise would not have been allowed under the terms of British sanctions - "in the interests of creditors who have lodged a complaint against the ship" Gibraltar authorities added without giving more details.
"The ship is now seized by the Admiralty Marshal" - the judge in charge of maritime affairs - "until further notice".
Dimitri Pumpianski is the boss of pipeline company TMK, and is also the subject of sanctions imposed by the EU against Russia's elite, or those who have close connections to Vladimir Putin.
Gibraltar's First Minister Fabian Picardo is visiting London this week and met with Britain's Foreign Minister Liz Truss on Tuesday. Afterwards Truss tweeted that she welcomed the seizure of the super yacht.
'People don't even have water there'
Exhausted Mariupol survivors continued to arrive by train in the western city of Lviv on Tuesday.
“In one compartment there were 10 or eleven people, with others in the corridor, but when you’re going to safety it doesn’t matter,” said one woman, Julia Krytska, who made it out with her husband and son. Her hands were shaking.
They were lucky to get out after volunteers found them in the besieged city, she said. “There’s no connection with the world," she said. “We couldn’t ask for help.”
The people of Mariupol don’t have a chance to be heard, she said. “They are in need of help. People don’t even have water there,” Krytska said.
