India, March 29 -- An earthquake that struck Myanmar on Friday has resulted in at least 694 deaths and over 1670 injuries, with the toll expected to rise as rescue operations continue. In neighboring Thailand, a high-rise under construction collapsed in Bangkok, leaving at least 6 dead.

"I have requested international support for relief efforts, and have allowed some offers for support from AHA Center and India," junta chief Min Aung Hlaing said in a video speech on state broadcaster MRTV.

The 7.7-magnitude earthquake struck on Friday at midday, with its epicenter near Mandalay, Myanmar's second-largest city. About 11 minutes later, a strong 6.4-magnitude aftershock followed.
