Ukrainian President Volodymyr Zelenskyy has called for tougher sanctions on Moscow after a Russian drone killed nine bus passengers, just hours after the two countries held their first direct peace talks in years.

Seven others were injured in the attack in Bilopillia in Ukraine’s northeastern region of Sumy, Zelenskyy said in a post on X on Saturday.

“All the deceased were civilians,” Zelenskyy said, adding that preliminary reports indicated a father, mother and daughter had been killed. “And the Russians could not have failed to understand what kind of vehicle they were targeting. This was a deliberate killing of civilians.”
