Korbsak said anti-government core leader Nattawut Saikua called him at 5 p.m. to inform about the plan, Thai News Agency reported.

For the main rally site Rajprasong area, it is estimated some 5, 000 protestors had remained there when the 3 p.m. deadline passed, said Police Major General Prawut Thavornsiri, spokesman of the national police operation command, the Bangkok Post's website reported.

However, more time would be given to the protestors in downtown Bangkok to leave the rally area, acting government spokesman, Panithan Wattanayakorn said as the deadline had passed.

Shortly after 2 p.m., military helicopters dropped leaflets on the encampment, urging the protestors to leave the Rajprasong site immediately.

The intense political situation in capital Bangkok has continued as troops' operations have continued to besiege the Rajprasong site aiming to pressure the protestors to end their over-two-month long rally.

The Center for Resolution of Emergency Situation from Sunday had warned the protestors to leave the Rajprasong rally site by 3 p.m..
