More than 1 million Rohingya refugees have fled to Bangladesh from Myanmar over several decades, including about 740,000 who crossed the border starting in August 2017, when the Myanmar military launched a brutal crackdown.
Conditions in Myanmar has worsened since a military takeover in 2021, and attempts to send them back have failed.
Last year, the United States said the oppression of Rohingya in Myanmar amounts to genocide after US authorities confirmed accounts of mass atrocities against civilians by the military in a systematic campaign against the ethnic minority.
Muslim Rohingya face widespread discrimination in Buddhist-majority Myanmar, where most are denied citizenship and many other rights.
