Ukrainian Foreign Minister Dmytro Kuleba said on Friday he had discussed additional military support for Ukraine with U.S. Secretary of State Antony Blinken.

"Heavy weapons on top of our agenda, and more are coming our way," Kuleba tweeted after the conversation, adding the issue of Ukraine's food exports was also discussed.

Early U.S. media reports said that Washington could announce a plan next week to send Kyiv weapons including Multiple Launch Rocket Systems, or MLRS, which are mobile artillery launchers that can fire dozens of kilometers farther than any current system in Ukraine's control.
