MUST WATCH! Myanmar: Protesters killed after police open fire during latest unrest

Police in Myanmar have fired tear gas, water cannon and stun grenades at pro-democracy protesters, killing at least 18 people, the UN has said.

The UN's human rights office said it has received "credible information" that the crackdown on people demonstrating against a military coup included live ammunition being fired into crowds, resulting in the deaths and dozens of injured people.

It is the highest single-day death toll among protesters, who demanded the restoration of Aung San Suu Kyi and her elected government.
