Myanmar's government is being accused of deliberately destroying evidence of possible "crimes against humanity" against the Rohingya minority.

Zeid Ra'ad al-Hussein, the UN high commissioner for human rights, says the Rohingya are being starved to death after a violent military crackdown, mass killings and rapes that caused a major refugee crisis.

The high commissioner has issued several condemnations of Myanmar's treatment of the Rohingya and is warning that the "ethnic cleansing" that began in August is ongoing.
