Polish Foreign Minister Radoslaw Sikorski said Poland sees no reason to sever diplomatic ties with Russia, noting that it has already limited the activities of Russian diplomats in several regions.

"Every time you are here, General, we can sleep a little more. We would like you to travel to all Ukrainian cities," Zelensky said at the annual Yalta European Strategy meeting.
