Three people were killed and 20 were wounded in a drive-by and a grenade attack early Thursday at the twin anti-government protest camps in Bangkok, medical officials and police said.
There were two attacks on protesters. The first was at 2.45am Thursday, when men in a white pickup truck drove by and shot into the guards' line at Khok Wua intersection.
Two people were gunned down. They were identified as Narayot Chanphet, 21, a PDRC guard who was shot in the chest, and Somkhuan Nuankanai, 51.
Just five minutes later, attackers fired two M79 grenade rounds into the anti-government support group camping out at the Democracy Monument.
The army arrived after the attacks, and sealed the area to allow investigators to gain access.
Phetphong Kamjornkitchakarn, a director at the city's Erawan Emergency Centre, said third man has died from wounds suffered in the attack near the Democracy Monument.
Mr Phetphong said the unidentified victim died at Hua Chiew Hospital.
The violence took the death toll during the six-month campaign of the People's Democratic Reform Committee (PDRC) to 28.
The military closed access to the site of the violence as dawn broke in Bangkok Thursday. (Post Today photo)
