Two people were killed and 40 others wounded in the eastern Thai province of Trat on February 22, after assailants launched a shooting spree and grenade attack at an anti-government rally site, local media reported.

The perpetrators arrived in a small pickup truck at the rally in Khao Saming district, about 300 kilometres east of Bangkok, firing guns and throwing grenades at the crowd before quickly escaping.

The attack was one of the most violent since anti-government protests began in late November last year, aiming to oust Prime Minister Yingluck Shinawatra.

The previous clashes and attacks against protesters primarily occurred at the main rally sites in Bangkok, with a fierce confrontation on February 18 killing two people and a grenade attack on February 21 wounding six.

Since the political violence started, 16 people have been killed and 695 injured, according to the Bangkok Emergency Medical Service.-VNA
