Myanmar’s junta has mobilized forces for offensives in the Mandalay, Sagaing and Magway regions at the same time that it has significantly reduced attacks in northern Shan state following a recent ceasefire there, members of the rebel People’s Defense Forces told Radio Free Asia.

Between Dec. 2 and Dec. 6, junta airstrikes and artillery killed 19 people and wounded at least 10 others in three townships in Mandalay region’s Myingyan district, according to an official from a pro-democracy paramilitary People’s Defense Force, or PDF, who requested anonymity for security reasons.

Among the dead were four rebel paramilitary fighters, the PDF official said.
