Ten Ukrainian soldiers in the Azovstal plant in the besieged Ukrainian city of Mariupol have surrendered with white flags, Interfax reported Monday, citing Alexander Khodakovsky, a commander of the "Donetsk People's Republic."

The Ukrainian military did not immediately respond to the report.

But Petro Andryushchenko, spokesperson for the mayor of Mariupol, was quoted by Ukraine 24 as saying the report is fake.
