As of 8pm last night, some 22 people had died and 172 were wounded in the latest clashes between red-shirt protesters and security forces, Bangkok's Emergency Medical Centre said.
Erawan Centre director Phetpong Kamchornkijkarn said one Liberian tourist was among those hurt yesterday, bringing the number of foreign casualties to four.
On Friday, a Canadian, a Pole, and a Burmese were wounded.
At midday, the toll stood at 17 people killed, all civilians, and 147 wounded.
Out of the 71 patients remaining at 18 hospitals, 11 were in intensive care at Charoenkrung Pracharak, Kluay Nam Thai, Phya Thai 1, Chulalongkorn, Wiparam and Kasemrat Rattanathibet hospitals.
Suwinai Busarakhamwong, director of Kluay Nam Thai Hospital, which treated 20 victims, said five patients were now in their ICU.
Meanwhile, the Emergency Medical Institute of Thailand has banned its medics from entering the dangerous "red zones", instructing them to wait outside till violence in areas where there are clashes to subside or for the wounded to be brought out for medical help.
Institute chief Chatree Charoencheevakul said yesterday the death of an emergency medic from Vajira Hospital during Friday's skirmishes had shaken emergency officials.
The institute had proposed to buy 100 bullet-proof vests but they wouldn't arrive in time for this conflict, he said.
The institute has offered Bt200,000 life insurance coverage for its 60,000 officials nationwide, with the institute contributing half of the Bt200 annual premium, he said. But the rescue officer who was killed had not joined this insurance scheme.
The rescue officer, identified as Boonthing Pansila, reportedly went on a motorcycle into the battle zone to assist the wounded but was shot in the neck, he said.
Going into the clash areas during gunfights was very risky, he said. The institute would consider contributing financial assistance to the dead man's family besides the Bt400,000 compensation from the government, he added.
Vajira Hospital director Dr Wanchai Charoenchokthavee said he ordered all ambulances and emergency personnel to withdraw from the protest site. He said he was saddened by Boonthing's death on duty despite wearing the white emergency uniform. His death had upset and demoralised co-workers, he said.
