The Thai anti-government group Tuesday afternoon poured their collected blood at the Government House' main gate, while the Thai Prime Minister has, however, performed his work as usual amid the continued mass rally.

The red-shiretd or United Front for Democracy against Dictatorship (UDD) protestors poured the blood at the main gate at about 4:55 p.m., local time, as a measure to pressure for a House dissolution and holding a fresh general election.

After that they went to pour their collected blood on the footpath in front of the ruling Democrat Party's headquarters in capital Bangkok at 18.41 p.m., local time, for the same reason.

On March 12 the UDD protestors traveled from the countryside to stage the rally in Bangkok as the Internal Security Act (ISA) has been enforced in eight provinces during March 11-23 to ensure security during the rally.

The ISA imposition has taken effect in the whole area of capital Bangkok and Nonthaburi, which is next to Bangkok.

Also, the ISA law has been enforced in some 21 districts of six other provinces near Bangkok, including Pathum Thani, Samut Prakan, Samut Sakhon, Chachoengsao, Nakhon Pathom, and Ayutthaya
