The shelling hit a post near Shan State’s border with Chiang Mai province in Thailand. 

An armed group fired artillery at a military post belonging to the Restoration Council of Shan State/Shan State Army (RCSS/SSA) on the Thai-Burma border on Wednesday evening, according to RCSS sources.

There were reportedly four attacks beginning at 5:30 p.m. on military post No. 11 in Mong Hta sub-township of Mongton Township, eastern Shan State.

“We are still investigating this shooting. They shot at us from Mong Tawt, where Burma Army and UWSA [United Wa State Army] forces are stationed. They open fire on us six times, but only four shells landed near our post. We don’t exactly know which armed group attacked us,” an RCSS/SSA officer said to SHAN.

The RCSS/SSA post is located near the Thai province of Chiang Mai, 30 minutes by motorbike from the village of Laktaeng, in the Piang Luang sub-district of Wieng Haeng district.

The RCSS/SSA is signatory to the Nationwide Ceasefire Agreement with the Burmese military and central government.

The Burma Army released a statement on January 25 warning all ethnic armed organizations to withdraw their forces to their central bases by February 12. The RCSS/SSA responded rejecting accusations that they had committed any wrongdoing requiring them to withdraw.
