KYIV, Ukraine — A Russian missile strike on port infrastructure in Odesa in southern Ukraine killed eight people and wounded 27, Ukraine’s emergency service said Saturday, as a Kremlin envoy was set to travel to Florida for talks on a U.S.-proposed plan to end the nearly four-year war,

The discussions are part of President Donald Trump’s administration’s monthslong push for peace that also included meetings with Ukrainian and European officials in Berlin earlier last week. Ukraine’s chief negotiator said late Friday that his delegation had completed separate meetings in the U.S. with American and European partners.

Ukrainian President Volodymyr Zelenskyy said much will depend on the U.S. posture after discussions with the Russians.

Speaking at a news conference in Kyiv with Portuguese Prime Minister Luís Montenegro, Zelenskyy said that “the key question remains how the United States responds after consultations with the Russians. At this point, I honestly don’t know, but I will know later today.”

Ukraine and Portugal signed an agreement to establish joint production of maritime drones, Zelenskyy said. “This is one of the most promising areas of defense cooperation. What matters now is delivering results, and all parts of Europe must have sufficient capabilities to counter any threats,” he said.

Oil rig, patrol ship targeted

Some of those wounded in Odesa were on a bus at the center of the strike late Friday, the emergency service said in a Telegram post. Trucks caught fire in the parking lot and cars were also damaged.

The port was struck with ballistic missiles, said Oleh Kiper, the head of the Odesa region.

Moscow did not immediately acknowledge reports of the attack. The Russian Defense Ministry said Saturday that over the previous day, it had struck unspecified “transport and storage infrastructure used by the Ukrainian armed forces,” along with energy facilities and those supplying Kyiv’s war effort.

Elsewhere, Ukrainian drones hit a Russian oil rig, the military patrol ship Okhotnik and other facilities, Ukraine’s General Staff said in a statement Saturday. It said the ship was patrolling in the Caspian Sea near an oil and gas production platform.

The drilling platform at the Filanovsky oil and gas field was also hit. The facility is operated by Russian oil giant Lukoil. Ukrainian drones also struck a radar system in the Krasnosilske area of Crimea, which Russia illegally annexed from Ukraine in 2014.

There was no immediate comment from the Russian government or Lukoil.
