Five Ukrainian border guards have been shot dead and seven more are wounded.
They were caught in a shootout with separatists in the eastern Ukrainian port city of Mariupol, Ukraine's border guard service said.
The border guards were reportedly attacked by pro-Russian separatists on a bridge.
(SOUNDBITE) (Russian) ALEKSANDER, MARIUPOL RESIDENT, SAYING:
"It is said that vehicles were shot. (Paramedics) have just taken a dead body out of the border service vehicle."
Mariupol is a major port for steel export. It had been reclaimed by Ukrainian forces just a day before.
It is also a strategic point because it connects major roads from Russia to Ukraine.
The city of 500,000 has long been a focus of clashes, and it's changed hands several times over the course of the conflict.
