A couple of "red-shirts" broke through the first blockade by the anti-riot police before a red-clad man on a wheelchair poured the first bucket of blood at the street in front of the Government House, between the first and second blockade.

After pouring down several backets of blood at Government House, the group left for the headquarters of the ruling Democrat Party.

Antiseptic devices and fire trucks are prepared at the party headquarters, according to Thai News Agency.

A horde of "red-shirts", led by their co-leader Nattawut Saikua, began to march by foot at 4:15 p.m. Tuesday from Phan Fah Bridge, the main rally site, toward the Government House to execute their high-profiled plan of blood pouring.

The blood is donated earlier the day by the "red-shirts" who are staging a mass rally in an effort to topple the government.

Since 8 o'clock in the morning, the red-clad supporters of the anti-government United Front of Democracy against Dictatorship ( UDD) have queued up to donate 10 cc blood each. The process was facilitated by medical teams from some local hospitals.

Nattawut said Monday afternoon that the blood pouring is a measure to step up pressure on the government during their mass rally.

It would be a symbolic action, making the cabinet ministers have to walk over the protesters' blood when they enter the Government House to work, Nattawut said.

The "red-shirts" movement has staged the rally to topple the Abhisit administration since March 12, urging the prime minister to dissolve the parliament and to call a fresh election.
