B ANGKOK — The death toll from the massive earthquake that hit Myanmar nearly a week ago rose Thursday to 3,085 as search and rescue teams found more bodies, the military-led government said, and humanitarian aid groups scrambled to provide survivors medical care and shelter.

Myanmar's military rulers have kept journalists out since the devastating earthquake, so CBS News' partners at the BBC went undercover to reveal the scale of the disaster.

The surprise announcement by the unelected government said the halt in fighting would run until April 22 to show compassion for people affected by last week's quake.

The 7.7 magnitude earthquake hit at midday Friday, causing widespread damage, including in the capital Naypitaw and the second largest city, Mandalay.

A 7.7 magnitude earthquake rattled much of Southeast Asia on Friday, flattening skyscrapers and leaving more than 1,000 people dead from Myanmar to Thailand.

Myanmar, also known as Burma, is in the throes of a prolonged and bloody civil war, which is already responsible for a massive humanitarian crisis.

The earthquake in central Myanmar last Friday killed 3,085 people and injured 4,715, the junta has said. Hundreds more are missing and the toll is expected to rise.

Myanmar’s ruling military has declared a temporary ceasefire in the country’s civil war to facilitate relief efforts following a 7.7 magnitude earthquake that has killed more than 3,000 people.
