As a civilian death toll continues to mount in Myanmar after the recent military coup, a UN envoy is warning that civil war is likely unless a solution is found fast. Our Choi Jong-un reports. An imminent bloodbath. That's how the UN envoy to Myanmar is describing the situation in the country, warning the risk of civil war is that an unprecedented scale. The official implored the UN Security Council to intervene using what she called potentially significant action. Her remarks came after the military launched airstrikes in Karen State for the first time in 20 years in retaliation for an earlier attack by ethnic Karen rebels. According to CNN on Tuesday, six people were killed and 11 were injured in the airstrikes. The Karen National Union, which controls an area in the southeast along the Thai border, leads a military base killing 10 soldiers and detaining eight others. The K&U says its actions were in response to appeals for help from opponents to the coup. Its armed faction is sending fighters to protect protesters while attacking Myanmar army positions and cutting off supply routes. With other armed groups vowing to join the protest movement if the military doesn't reverse course, fears of a return to armed ethnic conflict in the ethnically diverse nation has led to an accident as a foreigners. According to Reuters Wednesday, the US government has ordered all non-emergency government officials and their families to leave Myanmar. Germany and Norway are urging their nationals to avoid protest sites and come home when they can. Workers are also bearing the brunt of the violence. As the bloodshed continues, one local worker at a South Korean franchise bank was shot in the head, but it's unclear if she died. It's also unclear if she was targeted because she worked at a foreign bank. So far more than 520 people have died since the military overthrew the government of democratically elected leader An-San Su-Chi on February 1, holding Myanmar's decade-old experiment in democracy.
