Cambodian Prime Minister Hun Manet on Saturday expressed his condolences to the governments and peoples of Myanmar and Thailand over a massive earthquake on Friday afternoon.

In a condolence message to Myanmar's State Administration Council Chairman Senior General Min Aung Hlaing, the Cambodian leader said he was profoundly saddened to hear about the devastating earthquake that struck central Myanmar, resulting in the tragic loss of lives, injuries, and widespread damage to property.

"Our thoughts and prayers are with the victims, and we hope for the swift recovery of those injured," Hun Manet said.

"Cambodia stands in unwavering solidarity with the people of Myanmar during this challenging time," he said.

In another condolence letter to his Thai counterpart Paetongtarn Shinawatra, Hun Manet said he had learnt, with profound sadness, about the loss of lives, many injuries and severe damage to properties caused by the powerful earthquake in Bangkok.

"I wish the injured a full and speedy recovery," he said.

At least 1,644 people died, 3,408 were injured, and 139 remained missing after a 7.7-magnitude earthquake hit Myanmar on Friday, the Information Team of Myanmar's State Administration Council reported.

The devastating temblor also affected Thailand and other Southeast Asian countries. Shinawatra on Friday announced a state of emergency in Bangkok.
