The death of two Russian journalists killed in a mortar attack in eastern Ukraine was caught on camera by their cameraman.

Igor Kornelyuk, a 37-year-old correspondent for Russian state-owned TV channel Rossiya 24, and sound engineer Anton Voloshin came under fire as they were reporting from a checkpoint held by pro-Russian insurgents in Mirny, near the city of Luhansk.

With them was cameramen Viktor Denisov, who filmed the attack which he fled uninjured.

The footage starts with the cameraman trailing a separatist militiaman before to take cover behind an armoured vehicle that blocks the road.

Suddenly, mortar shelling starts to strike the site. During a break, an insurgent is seen dragging an injured man out of the fire line into the bushes at the side of the road.

Moments later, another blast hits the area.

Kornelyuk was rushed to a hospital, where he died after surgery. Voloshin reportedly died on site.

The deaths were followed by a late night telephone call between Ukrainian President Petro Poroshenko and his Russian counterpart Vladimir Putin who discussed a ceasefire in the eastern Ukraine.

The conversation resulted in Ukraine proposing a unilateral ceasefire to allow pro-Russian separatists a chance to lay down their weapons.
