Thai army may step in after attack

The chief of Thailand's army warned yesterday his troops "may use force" to quell political violence. It comes after three people were killed in a grenade and gun attack on protesters in Bangkok.

The rare official statement from General Prayut Chan-O-Cha followed a call by Thai election authorities for July polls to be postponed because of the unrest, AFP reported.

"I want to warn every group - especially those who use violence and war weapons against innocent civilians - to stop now because if the violence continues the military may be needed to come out... to restore peace and order," he said.

He said his troops "may need to use force to resolve the situation".

Unknown assailants fired two grenades into a rally camp yesterday at the Democracy Monument, followed by a burst of gunfire.
