Ethnic Karen guerrillas say they have captured a Myanmar army base near the border with Thailand, representing a morale boost for those opposing the military’s takeover of the country’s civilian government in February.
Myanmar’s military staged air strikes several hours later on villages in territory controlled by Karen forces, said a guerrilla spokesman, a senior Thai official and a relief worker.
A spokesman for the Karen National Union, the minority’s main political group seeking greater autonomy from Myanmar’s central government, said its armed wing attacked the base and burned it down just after dawn.
Casualty figures are not yet known, said the KNU’s head of foreign affairs, Padoh Saw Taw Nee.
The KNU, which controls territory in eastern Myanmar near the Thai border, is a close ally of the resistance movement against the coup that ousted the elected government of Aung San Suu Kyi. Its armed wing is called the Karen National Liberation Army.
Video shot from the Thai side of the border showed flames rising from the government position on the banks of the Salween River, amid the sound of heavy gunfire. The river marks the border with Thailand.
A report by the Karen Information Centre quoted an unnamed villager on the Thai side saying he saw seven government soldiers trying to flee the camp, which is opposite Thailand’s Mae Sam Laep village.
Padoh Man Man of the KNLA’s 5th Brigade, which launched the morning’s attack, said Myanmar’s military carried out air strikes in the early afternoon, but he did not know how many casualties there were.
He described the air raids as a “heinous war crime” and called for the international community to pressure the junta to stop them.
Sithichai Jindaluang, governor of Thailand’s Mae Hong Son province, confirmed at a news conference that Karen guerrillas had overrun the Myanmar base and said a woman on Thai soil was wounded by a stray bullet during the fighting. He said about 450 villagers have been evacuated from Mae Sam Lap for their own safety.
He also said a Myanmar military aircraft later bombed a Karen village.
Dave Eubank of the Free Burma Rangers, a humanitarian aid group with extensive experience in the area, said he could confirm there had been air strikes on Karen villages in two townships in Papun district.
He said Myanmar’s army was also staging ground attacks in the area. Neither he nor the governor had casualty figures available.
Fighting between the KNU’s armed wing and Myanmar’s military has been intense since February. Government air strikes began on March 27.
Myanmar jets have bombed and strafed Karen villages, and its army has deployed fresh battalions to the area, in possible preparation for a large-scale offensive.
Up to 25,000 villagers have fled their homes and are hiding in jungles and caves, according to Mr Eubank.
In response, the KNLA has kept up guerrilla attacks on Myanmar patrols and bases. The KNU has also given shelter to activists against military rule who have fled the government’s crackdown on the resistance movement in the cities.
There is a similar situation in northern Myanmar, where the Kachin minority claims to have captured several government outposts and been the target of air attacks.
The Karen and the Kachin are two of the bigger minority groups that have been seeking greater autonomy for decades, during which there have been periods of armed conflict punctuated by ceasefires.
