TOP WRAP 1-Red Cross heads again for Mariupol as Russia shifts Ukraine focus

By James Mackenzie

ZAPORIZHZHIA, Ukraine, April 2 (Reuters) - A Red Cross convoy travelling to the Ukrainian city of Mariupol will make another attempt to evacuate civilians from the besieged port on Saturday as Russian forces looked to be regrouping for new attacks in the southeast.

Mariupol, encircled since the early days of Russia's five-week-old invasion, has been Moscow's main target in Ukraine's southeastern region of Donbas. Tens of thousands there are trapped with scant access to food and water.

The International Committee of the Red Cross (ICRC) sent a team on Friday to lead a convoy of about 54 Ukrainian buses and other private vehicles out of the city, but they turned back, saying conditions made it impossible to proceed.

"They will try again on Saturday to facilitate the safe passage of civilians," the ICRC said in a statement. A previous Red Cross evacuation attempt in early March failed because the route was found to be unsafe.

Russia and Ukraine have agreed to humanitarian corridors during the war that have facilitated the evacuation of thousands of civilians.

The ICRC says its Mariupol operation has been approved by both sides, but major details were still being worked out such as the exact timing and destination of the convoy, which would be an undetermined location in Ukraine.

In an early morning video address, Ukrainian President Volodymyr Zelenskiy warned that Russian troops have moved toward the Donbas region and northeast in the direction of Kharkiv, Ukraine's second-largest city, where previous Russian strikes badly damaged urban areas.

"I hope they may still be solutions for the situation in Mariupol," Zelenskiy said. "The whole world has to react to this humanitarian catastrophe."

SHIFT FROM KYIV

Russian President Vladimir Putin sent troops on Feb. 24 for what he calls a "special operation" to demilitarise Ukraine.

The West calls it an unprovoked war of aggression that has killed thousands, uprooted a quarter of Ukraine's population and brought tensions between Russia and the United States to their worst point since the Cold War.

Aiming to lower nuclear tensions with Russia, the U.S. military has canceled an intercontinental ballistic missile test that it had initially aimed only to delay, the Air Force told Reuters.

But the United States and its European allies have sent Ukraine military assistance, including an additional $300 million dollars in aid announced by the Pentagon late on Friday. The new aid includes laser-guided rocket and anti-drone systems.
