MOSCOW, June 30 (Reuters) - A cameraman for Russia's state-owned Channel One television channel was killed overnight in Ukraine's eastern Donetsk region, the channel said on Monday, the third Russian journalist to die in the conflict.
The channel said on its website Anatoly Klyan, 68, was shot in the stomach after his film crew came under fire when they went to film near a pro-Kiev military unit in the region.
It said the journalists were accompanying a group of soldiers' mothers who were being driven to the unit "to meet their sons and take them home".
The bus carrying the mothers and the journalists withdrew after coming under fire as it approached the base. Klyan died when a group of people came under further automatic rifle fire after leaving the bus, Channel One said.
Russia has protested against the killings of its journalists, calling on Kiev to stop operations in Donetsk and the region of Luhansk, where separatists have seized state buildings and weapons arsenals.
On June 17, a Russian correspondent and a sound engineer for state television were killed by mortar fire in clashes near Luhansk.
Sporadic violence has continued in eastern Ukraine despite a ceasefire declared by Ukrainian President Petro Poroshenko on June 20 to allow for peace talks with the rebels. The ceasefire is due to expire on Monday evening. (Reporting by Jason Bush; Editing by Elizabeth Piper and Paul Tait)
