Ukraine war updates: Macron says Kyiv should be allowed to use Western weapons on Russian military sites; U.S. weighs further sanctions

This is CNBC's live blog tracking developments on the war in Ukraine. See below for the latest updates. 

Ukraine should be allowed to use Western arms against Russian military sites used to target Ukraine, French President Emmanuel Macron said late Tuesday, bowing to ongoing requests from Kyiv.

"How can we explain to Ukraine that they need to protect their cities . . . but that they don't have the right to attack where the missiles are coming from? It's as if we were telling them we're giving you arms but you cannot use them to defend yourself," Macron said late Tuesday during a press conference in Meseberg, Germany.

Macron was joined by German Chancellor Olaf Scholz, who agreed Ukraine should be allowed to defend its territory as long as it respected the conditions of the weapons suppliers. 

Russian President Vladimir Putin warned of serious consequences if Russia is struck with Western weapons.

That came as Ukrainian President Volodymyr Zelenskyy's made his two-day tour of Europe, during which he visited Spain, Portugal and Belgium and received more promises of military aid.

Elsewhere, the U.S. and its allies may impose more sanctions and export controls to curtail trade between Russia and China, a White House official said Tuesday, according to Reuters.

Russia's naval forces destroyed two Ukrainian sea drones in the northwest of the Black Sea, as they headed for the Crimean Peninsula, Russia's Ministry of Defense said in a Google-translated Telegram post.

Russia uses the Sevastopol naval base in the Crimean Peninsula, which Moscow annexed in 2014, for its Black Sea fleet.

Ukrainian military has previously reported instances of its sea drones striking and sinking Black Sea Fleet ships off the Crimean Peninsula.
