More than 2,000 people in Myanmar have been killed following a magnitude 7.7 earthquake that affected areas as far as Thailand and China.

Myanmar's military government has proclaimed a week of national mourning, with a minute of silence scheduled for later on Tuesday at 12:51 local, the exact time the tremor struck on Friday, BBC reported.

 In neighboring Thailand, 20 people have perished, and many have been evacuated from Bangkok's shattered buildings. Rescuers in both nations are still continuing their hunt for survivors, though hopes are diminishing since the vital window—the first 72 hours following a quake—has passed.

The UN believes the earthquake has exacerbated "an already dire crisis" in Myanmar, which is in the midst of a four-year civil conflict, according to BBC.

Despite the wreckage, reports indicate that the country's military officials are still conducting air attacks against pro-democracy rebel forces.
