Clashes between the ethnic guerrilla Karen National Liberation Army (KLNA) and the Tatmadaw - as the Burmese Army is known - were recorded throughout Wednesday in Kayin (Karen) State, about 2.5 kilometers from the Thai border.
The rebel group launched a drone attack against a military base in the Burmese district of Langpai, according to the statement posted on Wednesday night on the Facebook profile of the Naresuan special forces, of the Thai Army.
The Thai military states in the text that they "are attending to 197 Burmese refugees for humanitarian reasons" who crossed into Thai territory "temporarily".
At the same time, the Thai Army has increased security and patrols in the border area of Tak province.
This confrontation comes after the Burmese military junta announced a new truce until May 31 on Tuesday with the aim of continuing reconstruction work after the devastating earthquake that shook the country at the end of March.
The junta announced an initial ceasefire on April 2, after the March 28 earthquake, which left more than 3,700 dead and nearly 200,000 displaced, which had expired last Wednesday, as confirmed to EFE by the spokesman for the military regime, Zaw Min Tun.
Rebel forces and the pro-democracy opposition National Unity Government denounced during the first truce that the Army violated the cessation of hostilities on numerous occasions.
The 2021 military coup in Myanmar ended a decade of democratic transition and exacerbated the guerrilla war that the country has been experiencing for decades.
