Putin meets with Belarus leader to discuss 'strategic partnership'

The Ukrainian port city of Odesa came under renewed Russian missile attack early Sunday, just hours before President Vladimir Putin was due to hold a summit with his Belarus ally Alexander Lukashenko. At the meeting in Saint Petersburg, the pair are discussing the "strategic partnership and alliance" between their countries, according to the Kremlin.

It will be the first time they have met since Lukashenko helped end a dramatic mutiny by Russian mercenaries from the Wagner group. Hours before their meeting, Russian strikes targeted Odesa, which has been bombed several times since the start of the conflict.

Ukraine's Southern Operational Command said Odesa was targeted with at least five types of missile, including Kalibr cruise missiles.

"Air defense forces destroyed a significant amount of the missiles," it said. "The rest caused damage to port infrastructure," and several buildings, adding that a missile had hit the Orthodox cathedral in the city center.

The strategic port has come under repeated attack since Moscow pulled out of a grain export deal last week. The head of Ukraine's presidential office, Andriy Yermak, repeated Kyiv's call for more missiles and defense systems after the latest attack on Odesa.

"The enemy must be deprived of the ability to hit civilians and infrastructure. More missile defense systems, as well as ATACMS - this will help Ukraine," he said on Telegram, referring to the long-range tactical missiles that Kyiv wants Washington to supply.

Kyiv has accused Russia of targeting grain supplies and infrastructure vital to any resumption of Ukrainian grain exports. Moscow has claimed it only targeted military sites.

The attack on Odesa comes a day after a Ukrainian drone strike blew up an ammunition depot in Crimea, forcing the evacuation of the surrounding population and temporary suspension of rail traffic on the peninsula annexed by Russia in 2014.
