Russian President Vladimir Putin would not refuse a meeting with Ukrainian President Volodymyr Zelenskyy, but any such contact would have to be substantive with specifics, said Russian Foreign Minister Sergei Lavrov.

The foreign ministers from Russia and Ukraine have discussed the possibility of the Putin-Zelenskyy meeting, said Lavrov.

At the press conference, Lavrov was also asked about the Mariupol hospital attack. The Ukrainian side has insisted that three people including a child were killed in a Russian strike on a maternity and children's hospital in the city of Mariupol.

Lavrov has denied the accusation, saying that the hospital building had for days been under the control of "ultra-radical" Ukrainian forces who had emptied out the doctors and patients.
