The leader of Myanmar's ruling military junta, Min Aung Hlaing, is due to travel to Bangkok on Thursday for a regional summit.
The death toll from the devastating earthquake that hit Myanmar last week has surpassed 3,000, the military junta said on Thursday, as NGOs scramble to provide healthcare and shelter to survivors.

Last Friday's 7.7 magnitude earthquake — one of the biggest in a century in the war-stricken Southeast Asian nation — brought down thousands of buildings, buckled roads and destroyed bridges in multiple regions.

At least 3,085 people have died, while 4,715 have been injured and 341 are missing, the military said in a short statement.

Local media reports of casualties have been much higher than government figures. With communication networks affected by the disaster and many places still difficult to reach, the official death toll could rise sharply as more information arrives.

The World Health Organization (WHO) said an initial assessment showed that four hospitals and one health centre had been completely destroyed, while another 32 hospitals and 18 health centres had been partially damaged.

"With infrastructure compromised and patient numbers surging, access to health care has become nearly impossible in many of the worst-hit areas," the UN agency said.

"Thousands of people are in urgent need of trauma care, surgical interventions and treatment for disease outbreaks," it said, warning that cholera was a particular risk.

At least 1,550 international rescuers were operating alongside local citizens on Thursday, the military said. Rescue supplies and equipment have been sent by 17 nations.

The earthquake has exacerbated an already dire humanitarian crisis, with more than 3 million people displaced from their homes and nearly 20 million in need before the disaster, according to the UN.
