The clash came after Thai Prime Minister Abhisit Vejjajiva decided to end the two-month standoff following his withdrawal of the Nov. 14 election proposal Thursday.
Abhisit proposed his reconciliation roadmap and offered the Nov. 14 poll date on May 3. He later announced house dissolution date between Sept. 15 to 30.
"Red-shirts" movement accepted the house dissolution and poll date but refused to end the two-month-long rally unless Deputy Prime Minister Suthep Thuangsuban surrenders to police.
On Thursday night, the Centre for Resolution of Emergency Situation (CRES) declared extension of state of emergency to more provinces, in addition to existing areas in capital Bangkok and nearby provinces, which was announced on April 7, 2010.
These additional provinces include eastern Chonburi province, northern Chiang Mai province, northeastern Udon Thani, and Nakhon Ratchasima province.
