Watch: CCTV footage from Bangkok blast site

A powerful bomb exploded outside a Hindu temple in the Thai capital in Bangkok on Monday, killing at least 12 people. The bomb exploded at 7 pm (5:30 IST) outside Erawan Shrine, which is dedicated to Lord Brahma, in the downtown Chidlom district, police said.

The temple is located on a main road through Bangkok's commercial hub and is surrounded by three major shopping malls.

There was no immediate claim of responsibility. Thai forces are fighting a low-level Muslim insurgency in the predominantly Buddhist country's south, although those rebels have rarely launched attacks outside their ethnic Malay heartland. Monday's blast was near the Erawan shrine at a major Bangkok intersection.

"All I can say now is there has been an explosion in central Bangkok involving a motorcycle bomb," deputy national police chief Aek Angsananond told Reuters. He said there had been fatalities, but could not confirm details.

A policeman at the scene and a rescue worker said 12 people had been killed. Media put the number of the wounded at 20.

A Reuters witness at the scene said she saw pieces of human flesh near the blast site, and a soldier later told onlookers to move back, saying they were checking for a second bomb.

"We are now looking for another two to three bombs as we have found one suspicious object," national police chief Prawut Thawornsiri told Reuters.

"There could be another explosion, so we have blocked off the crime scene and are asking bystanders to move back."
