A couple in Mondulkiri province’s Keo Seima district was killed on Wednesday when the husband detonated a home-made grenade following a heated argument caused by jealousy.

Deputy provincial police chief So Sovan said the blast killed Noeun Lan, 32, from Kampong Cham province’s Koh Sotin district, and his wife Sim Thib, 37, from Prey Veng province’s Sithor Kandal district.

He said the grenade was made of TNT powder, adding that Lan had attempted suicide on several occasions.

“Forensic police examined the scene and found two small batteries used to blow up the home-made grenade. We determined that it’s a suicide initiated by the husband,” he said.

Keo Seima district police chief Van Danin said the couple’s neighbours often saw them quarrel, with the husband allegedly suspicious that his wife had an affair with another man.
