At least 12 killed in protests in Myanmar

Families and friends grieved on Saturday over two men killed in an overnight raid in Myanmar's largest city Yangon.

The two who died in police firing were among at least 12 people killed in Myanmar by security forces, witnesses and media reported.

Five people were shot dead and several injured when police opened fire on a sit-in protest in Mandalay, Myanmar's second-biggest city, witnesses told Reuters.

Than Saw is the mother of one of those who died in Yangon, trishaw peddler Si Thu.

"I told my son that we have nothing and we will die if we go against them. I would go and shoot back at them if I had a gun. Now we can't do anything as we don't have guns. Tell me, do we always have to keep silent and die? Why are we dying for doing the right thing?"

The deaths came as the leaders of the United States, India, Australia and Japan vowed to work together to restore democracy in the Southeast Asian nation.

More than 70 people have been killed in Myanmar in widespread protests against a Feb. 1 coup by the military.

That's according to the Assistance Association for Political Prisoners advocacy group.

Mahn Win Khaing Than, who was appointed acting vice-president by representatives of Myanmar's ousted lawmakers, addressed the public for the first time on Saturday from hiding via Facebook on Saturday, vowing to pursue a "revolution" to overturn the junta, and adding that, "This is the darkest moment of the nation and the moment that the dawn is close."
