More than a dozen Ukrainian servicemen have been killed in an overnight clash at a checkpoint in the east of the country.
Militants apparently armed with mortar shells and grenades stormed the site in one of the bloodiest incidents the Ukrainian military has seen since tensions began.
It is terrifying to speak of... Three of my friends have fallen and I can't even collect their bodies because everyone wants to film them. The commander of the combat unit – half of his head is missing and he was only 27 years old.
