Despite the Ukrainian forces suspending their "anti-terrorist" operation in eastern Ukraine for the Easter holidays, at least five people have reportedly been killed in a fierce gun battle which erupted in the city of Slavyansk.
The shooting is said to have taken place on the outskirts of the city which is controlled by armed pro-Russian protesters.
"Three residents of Slavyansk were shot dead by unidentified gunmen who attacked a block-post in the north of the town. Another person was wounded and is in hospital in critical condition," a report on vesti.ru says.
Two of the attackers are said to be dead following the incident when the anti-Kiev protesters who were manning the checkpoint returned fire.
There has been no independent confirmation of the incident although local reports suggest there was intense gunfire.
