As the road shook beneath him, Ko Zeyer sped past crumbled buildings, buckled roads and gaping sinkholes toward his hometown of Sagaing, the epicenter of the most powerful earthquake to hit Myanmar in a century.

The death toll from the massive earthquake that hit Myanmar nearly a week ago rose Thursday to 3,085 as more bodies were found by search and rescue teams, the military-led government said. In a short statement, the military said another 4,715 people have been injured and 341 are missing.

Extreme heat and heavy rain in Myanmar could cause disease outbreaks among earthquake survivors camping in the open, global aid bodies warned on Thursday.

Myanmar's military is limiting critically needed humanitarian aid for earthquake victims in areas where it sees opposition to its rule, the United Nations human rights office said on Friday.The U.N. Office of the High Commissioner for Human Rights also said it was investigating 53 reported attacks by the junta against its opponents since the earthquake struck on March 28,

Myanmar junta chief Min Aung Hlaing has also rejected calls for a ceasefire to facilitate the delivery of desperately needed relief supplies.

It was unclear whether the cease-fire would be honored. It came a day after soldiers fired at a Chinese Red Cross aid convoy, and amid multiple airstrikes.
