Security was tight around a military base in south-western Cambodia on Sunday, a day after a huge explosion there killed 20 soldiers, wounded others and damaged nearby houses.
Guards sought to keep media away from the site in Kompong Speu province.
Cambodian Prime Minister Hun Manet said in a Facebook post on Saturday that he was “deeply shocked” when he received the news of the blast in the province’s Chbar Mon district. It was not immediately clear what caused it.
Images from the scene showed several badly damaged buildings on the base, at least one with its roof blown off, and soldiers receiving treatment in a hospital. Other photos showed nearby houses with holes in their roofs.
He added that 25 villagers’ homes were damaged as well. Photos of the base showed the damaged structures in a large field, apparently with no civilian structures close by.
Another villager, who asked to be named only as Sophal, told AP he had heard a sharp sound, and when he saw smoke rising from the direction of the army base, he realised it was an explosion at the arms depot.
He then ran back to his house from the small shop where he sells food and drink to shelter inside with his wife and two children.
He said the military immediately closed the road to the base and “villagers were in a panic, seeking a safe place”.
He then moved his family to his parent’s home, farther away from the base. When he returned to his own house hours later, he found it undamaged but other villagers’ houses had broken windows, doors and roofs, he said.
Cambodia, like many countries in the region, has been suffering from an extended heat wave, and the province where the blast took place registered a high of 39C on Saturday.
While high temperatures normally cannot detonate ammunition, they can degrade the stability of explosives over a period of time, with the risk that a single small explosion can set off a fire and a chain reaction.
Kiripost, an online English language news service, quoted villager Pheng Kimneang as saying a major explosion occurred at about 2.30pm, followed by smaller blasts for about another hour.
Hun Manet offered condolences to the soldiers’ families and promised the government would pay for their funerals and provide compensation both to those killed and those wounded.
A graduate of the US military academy at West Point, he was army commander before he was elected last year to serve as prime minister, succeeding his father Hun Sen, who led Cambodia for 38 years before stepping down.
US ambassador Patrick Murphy, in a post on the social platform X, extended condolences to the families of the soldiers affected by the explosion.
