A prominent separatist commander has been killed in eastern Ukraine, four days after another pro-Russian military leader was blown up by a car bomb.
Mikhail Tolstykh, known as Givi, died in his office in an explosion described by rebel authorities in Donetsk as a terrorist attack.
Eastern Ukraine has seen its bloodiest period of clashes since 2015, with at least 35 deaths in little over a week.
Rebels have blamed Ukraine’s security services for both bomb attacks.
Oleg Anashschenko, who was de facto defence minister of the self-proclaimed Luhansk People’s Republic (LNR), had been driving in Luhansk when his car blew up on Saturday.
Why have so many rebel commanders been killed?
- Rebel commander Anashschenko killed in Ukraine blast
- Ukraine rebel fury at Motorola murder
- New, bloody chapter in eastern Ukraine
The two military figures blown up in the past few days are the latest in a series of rebel commanders killed in eastern Ukraine. The conflict between Ukrainian troops and pro-Russian separatists erupted after Russia annexed Ukraine’s southern Crimea peninsula in March 2014.
Ukrainians in Kiev have put the most recent killings down to infighting among rebels. Military commentator and MP Dmytro Tymchuk suggested that Givi had begun ignoring orders, particularly during the escalation of fighting at Avdiivka last week, just outside Donetsk.
