A Burmese warship opened fire on a Thai fishing trawler killing at least one fisherman before capturing 31 others.

The vessels from Thailand had reportedly strayed into Myaanmar territory before naval ships from the erratic nation - currently locked in a civil war - began shooting at them on Saturday night.

Thai officials pulled two injured men from the water while a third man drowned. They said that at least 31 others had been captured and detained in Myanmar.

Footage shows the aftermath of the clash as the Thais were rescued. Thai battleships were also patrolling the water on Sunday, December 1.

Thai navy spokesman Thanatip Sawangsang said the boats has been operating between four and 5.7 nautical miles (7.4 to 10.6 km) inside Myanmar's territorial waters.

One of the boats, with 31 fishermen on board, was detained by troops. Officials are now negotiating their release.

Myanmar has fallen into civil war following the removal of democratically elected leader Aung San Suu Kyi, a Nobel Peace Prize winner, with a military coup in 2021.

Soldiers responded with barbaric force on protesting civilians leading to widespread condemnation and financial sanctions. Rebel groups and civilian militias around the country have since been locked in a series of ongoing clashes with the ruling military.

Aung San Suu Kyi has since been jailed for 33 years on politically motivated charges and is likely to die behind bars unless the army is toppled - a tragic end the politician hailed by Barack Obama as an 'inspirational icon of democracy'.
