Burmese security forces kill at least 65 civilians in the Hlaingthaya massacre.

The Hlaingthaya massacre was a mass killing of civilians on 14 March 2021, in Hlaingthaya Township, Yangon, Myanmar. During the massacre, Myanmar Army troops and Myanmar Police Force officers killed at least sixty-five individuals. The massacre became one of the deadliest domestic incidents to occur in the aftermath of the 2021 Myanmar coup d'état, and marked a serious escalation in the military's violence against civilians resisting the coup. The violent crackdown also precipitated a mass exodus of factory workers, residents, and businesses from Hlaingthaya, a major factory hub in the country.

March 14 is the 73rd day of the year in the Gregorian calendar; 292 days remain until the end of the year.
