Watch: UN Security Council meets to mark second anniversary of Russia invading Ukraine

Watch as the United Nations Security Council held a meeting on Ukraine, marking the second anniversary of Russia's invasion.

David Cameron was expected to be among the speakers who would appear at the evening's meeting, as well as his Ukrainian counterpart Dmytro Kuleba.

The two-year anniversary of Vladimir Putin’s full-scale invasion comes as the US announced its largest single package of sanctions against Moscow.

Sanctions and export controls have been announced to slow Russia down, "making it harder for them to fight their war of choice," Deputy US Treasury Secretary Wally Adeyemo said.

US officials said more than 500 targets will be sanctioned in the latest package including from Russia's military industrial complex and companies in third countries that facilitate the Kremlin’s access to goods it wants.

Additionally, EU member states approved a 13th package of Ukraine-related sanctions against Moscow on Wednesday, banning nearly 200 entities and individuals accused of helping Russia procure weapons or of involvement in kidnapping Ukrainian children.

Moscow denies any kidnapping has taken place.

In response to the latest round of sanctions by the bloc, Moscow banned more EU officials and politicians from Russia.

The Russian foreign ministry said: "The European Union is continuing its fruitless attempts to put pressure on Russia through unilateral restrictive measures."
