At least one person killed as military forces continue to fend off an alliance of ethnic fighters in western Shan state.

Ethnic armed fighters have launched fresh attacks at several locations across northern Myanmar early Thursday, killing at least one civilian staff member at an elite military college, an army spokesman said.

The Northern Alliance, a collective of armed groups active in the region, claimed one attack on the Defence Services Technological Academy in Pyin Oo Lwin, western Shan state, where one person died, and attacks in four other places nearby.

Myanmar’s military frequently clashes with groups who claim to be fighting for greater autonomy for ethnic minorities in the area but Pyin Oo Lwin, a military town also popular with tourists, has been mostly unaffected.

A months-long ceasefire agreement ended in June.

“We aim to change battlefronts, as the Burmese military are increasing their offensives in ethnic areas during these days,” Mong Aik Kyaw, a spokesman for the Northern Alliance told Reuters news agency via phone.

Military spokesman Tun Tun Nyi told Reuters via phone that fighting was ongoing in Naung Cho township near the Gokteik viaduct, a popular tourist site.

Clashes with the Northern Alliance have intensified across Shan state since 2016, claiming hundreds of lives across an arc of land in the long border region with China.
