BANGKOK: Explosions and heavy gunfire rattled Bangkok on Saturday as pro- and anti-government protesters clashed on the eve of controversial Thai elections seen as unlikely to end a cycle of violence in the kingdom after months of opposition rallies.

Bystanders, security personnel and journalists raced to take cover in a shopping mall after a masked gunman man began spraying bullets from an assault rifle during confrontations between government supporters and opposition demonstrators, according to a reporter.

At least six people were injured as a busy intersection in a northern suburb of the capital was turned into a battle zone with volleys of sustained gunfire ricocheting off buildings for over an hour in a daylight attack that sent shockwaves across the city.

Tensions are high in the capital ahead of snap elections on Sunday, which opposition demonstrators have vowed to block as they seek to prevent the likely re-election of Prime Minister Yingluck Shinawatra.

Bangkok has been rocked by weeks of sometimes bloody political violence during rallies by a loose coalition opposed to Yingluck and the enduring influence of her brother Thaksin Shinawatra — a former premier ousted by the military in 2006.

Saturday’s clashes happened after demonstrators blocking ballot boxes from being delivered from the Lak Si district office — one of 50 in the capital — were confronted by a group of some 200 government supporters, some armed with sticks and metal bars.At least two explosions were heard in the area before the firing began.

“The clash point is the intersection, gun shots seemed to be fired from both sides,” said Sunai Phasuk, a senior researcher with New York-based Human Rights Watch, who was at the scene.

He said a reporter was among the injured.

The firing started after talks between the rival groups broke down in the area, which is roughly split between Yingluck’s supporters and those backing the opposition protests, Sunai added.

At least 10 people have been killed and hundreds injured in clashes, grenade attacks and drive-by shootings since the opposition rallies began three months ago.

The unrest is the latest round of political instability to hit Thailand since royalist generals ousted Thaksin seven years ago, unleashing a cycle of sporadically-violent street protests.

In 2010 clashes and a military crackdown on pro-Thaksin Red Shirts demonstrating against the previous government left more than 90 people dead and nearly 1,900 injured.—AFP
