YANGON: The United State on Wednesday ordered the departure of non-essential diplomats from Myanmar, amid growing violence following the military coup to oust civilian leader Aung San Suu Kyi.
Daily protests demanding the restoration of the elected government have been met with a military crackdown that has left more than 520 civilians dead in the weeks since the February 1 coup.
The junta's violent response has triggered international condemnation -- and threats of retaliation from some of Myanmar's myriad ethnic armed groups.
The US State Department said it was ordering the departure of "non-emergency US government employees and their family members".
The decision was taken to protect the safety and security of staff and their families, the State Department said.
World powers have repeatedly condemned the violent crackdown on dissent and hit top junta cadres with sanctions.
But the pressure has not swayed the generals. Saturday, the annual Armed Forces Day, saw the biggest loss of life so far, with at least 107 people killed.
The spiralling bloodshed has angered some of Myanmar's 20 or so armed ethnic groups, who control large areas of territory mostly in border regions.
Three of them -- the Ta'ang National Liberation Army, the Myanmar Nationalities Democratic Alliance Army and the Arakan Army (AA) -- on Tuesday threatened to join protesters' fight unless the military reined in its crackdown.
While the trio has yet to act on their warning, two other outfits -- the Karen National Union (KNU) and the Kachin Independence Army (KIA) -- have stepped up attacks on military and police in recent days.
A police station in Bago was reportedly hit with a rocket attack that injured five officers on Tuesday, though it was not clear who was responsible.
The KNU, one of the biggest rebel groups, took over an army base in eastern Kayin state at the weekend, prompting the military to respond with air strikes.
Further strikes were launched on Tuesday, but Padoh Saw Taw Nee, the KNU's head of foreign affairs, said the group would continue its position of "strongly supporting people's movement against (the) military coup".
The KNU's Fifth Brigade put out a statement on Tuesday condemning the air strikes and warning it had no option but to "confront these serious threats" posed by the military.
