Rescue teams continued to search for bodies buried in a building in Thailand that collapsed during the earthquake.

Footage shows volunteers scouring the rubble of the crumbled State Audit Office in the capital Bangkok, on April 8.

They said they have retrieved several body parts, which have been turned over to the Police General Hospital's Institute of Forensic Medicine.

Thai officials said that 22 people have been confirmed dead in the collapse, with nine in hospital with serious injuries. A further 73 are still missing, trapped in the debris of the collapsed office and apartment block tower.

The 7.7 magnitude quake struck Myanmar on March 28, around 12:50 pm local time. More than 5,000 people are believed to have died in the country.
