A number of motorists in Bangkok and around the country switched on their headlights in a silent gesture to induce negotiations between caretaker Prime Minister Thaksin Shinawatra and his opponents.

"Well, my headlights are on and I believe talking is the best way to resolve any problem," Surayud said.

He was talking to reporters before chairing a meeting on a civic campaign designed to resolve unrest in the deep South.

"The relevant parties are all leading figures and are therefore able to think for themselves on what they should do in order to uphold the national interest," he said, ruling out the role of a mediator to map out a solution.

"It is not in the best interests of the country for the turmoil to persist. Opposing sides should stop causing divisions and start talking to one another," he said.

Thaksin, in reaction of Surayud's suggestion, said he was ready to talk with his opponents. He could host talks, or accept an invitation if the opposition hosted them.
