How aid becomes a weapon in Myanmar's war zone

In the immediate aftermath of an earthquake, there is a 72-hour "golden window" when those trapped under rubble are most likely to survive.

But in the 72 hours after a 7.7 magnitude quake struck Myanmar on Friday, rescue and relief workers seeking access to some of the worst-hit areas were blocked by military authorities, multiple aid and human rights groups told the BBC.

This was despite a rare plea for international humanitarian assistance by junta chief Min Aung Hlaing.
