The Thai government is aware of an offer on Tuesday by a group of senators to broker talks with thousands of protesters but has no official position on whether to accept it, a government spokesman said.
"We have no position on that yet. The prime minister has been informed but does not have an immediate position on it," said government spokesman Panitan Wattanayagorn.
"Our top priority right now is to end the rioting that traps civilians in the area. But we are not rejecting or accepting the senators'' offer yet."
A leader of "red shirt" anti-government protesters said on Tuesday they had agreed to participate in talks brokered by the speaker of the Senate in order to prevent further casualties.
At least 38 people have died in the latest flare-up in violence in Bangkok since May 13.
