The New Arab's live coverage of the latest from the Russian invasion of Ukraine concludes for today.
Here are the key developments from Tuesday:
Ukrainians 'surrounded' in Mariupol
Ukrainian forces are "surrounded and blocked" in Mariupol as Russian forces push to take the southeastern port city, Mykhaylo Podolyak, an official from President Volodymyr Zelensky's office, tweets.
Zelensky says he believes "tens of thousands" of people in the city have been killed and makes another plea for weapons.
'Credible information' on chemical weapons
The United States has "credible information" that Russia "may use... chemical agents" in its offensive to take Mariupol, US Secretary of State Antony Blinken says.
He tells reporters he is not able to confirm accusations that Moscow has already used chemical weapons there.
The world's chemical weapons watchdog, the OPCW, says it is "concerned" over reports of the use of chemical weapons in Mariupol.
'All options on table'
Britain's armed forces minister James Heappey tells Sky News that if evidence of chemical weapons use emerges, "all options are on the table" as a response.
"There are some things that are beyond the pale, and the use of chemical weapons will get a response," he says.
Over 400 bodies in Bucha
The mayor of the town of Bucha, where dozens of bodies were found after Russia's withdrawal from northern Ukraine, says more than 400 people have been found dead so far and 25 women have reported being raped.
Zelensky says investigators have received reports of "hundreds of cases of rape" in areas previously occupied by Russian troops, including sexual assaults of small children.
Residents flee east
Residents stream out of east Ukraine's Kramatorsk and Sloviansk as fears grow the cities will be key targets of a major new Russian offensive.
The Pentagon says Russia is building up its forces in the eastern Donbas region, as it switches its focus to a region where pro-Russian rebels have been fighting Ukrainian forces since 2014.
Over 870,000 returnees
More than 870,000 Ukrainians who fled abroad since the start of the war have returned to the country, Ukraine's border force says.
Spokesman Andriy Demchenko says that 25,000 to 30,000 Ukrainians are returning each day, with growing numbers of women, children and elderly among them.
German president 'not wanted' in Kyiv
German President Frank-Walter Steinmeier says he offered to visit Ukraine with other EU leaders but was told by Kyiv his trip was "not wanted".
Steinmeier, a former foreign minister under ex-chancellor Angela Merkel, was long known for championing ties with Moscow. The snub comes as Chancellor Olaf Scholz is under increasing pressure for not having visited Ukraine.
Talks 'extremely difficult': Kyiv
Kyiv says talks with Russia to end the war are "extremely difficult".
"Negotiations are extremely difficult," Ukrainian presidential adviser Mykhaylo Podolyak says.
Putin says Ukraine's "inconsistency on fundamental points" is creating "certain difficulties in reaching final agreements".
