Mandalay, Myanmar's second city, saw the biggest turnout with activists staging a sit-in protest after two minutes of silence in honor of people killed by police and military units, video placed on social media showed.

Police used stun grenades and tear gas against demonstrators in the historic temple town of Bagan, a UNESCO World Heritage Site, famous for its ancient Buddhist temples.

A 19-year-old man and a woman sustained serious injuries as they were shot, but it was not clear whether they were hit by rubber bullets or live ammunition.

At least three people were arrested in Kyauktada Township in downtown Yangon late Saturday into Sunday, residents said, with no reason given for the arrests.

"They are asking to take out my father and brother. Is no one going to help us?" one woman screamed as two of the three, an actor and his son, were led away, according to Reuters.

Soldiers also looked for but didn’t find a lawyer who worked for former de facto leader Suu Kyi's National League for Democracy, Sithu Maung said in a Facebook post.

The Assistance Association for Political Prisoners advocacy group said Saturday that more than 1,700 people had been detained under the junta, according to its figures.

"Detainees were punched and kicked with military boots, beaten with police batons, and then dragged into police vehicles," AAPP said in a statement. "Security forces entered residential areas and tried to arrest further protesters, and shot at the homes, destroying many."

State television MRTV reported Saturday that Myanmar authorities had exhumed the body of Kyal Sin, also known as Angel, who died while wearing a T-shirt that read, “Everything will be OK.”

Kyal Sin, who has become an icon of the protests, was shot in the head and died Wednesday.

Police, doctors and a judge determined that she was killed by “those who do not want stability” and not police, MRTV said. Officials had said her wound was to the back of her head, and therefore couldn’t have been caused by police. Photos published by Reuters, however, show Kyal Sin had the back of her head turned to a line of security forces moments before she was shot.

Myanmar has been consumed by chaos and violence since February 1, when the military overthrew the civilian government and detained Suu Kyi and other high-ranking NLD officials. Military officials say widespread fraud occurred in last November’s election, which the NLD won in a landslide. Election officials have denied any significant irregularities.
