BREAKING: Deadly Blasts Rock Face Off Between Pro-Government Protesters, Red Shirts At Silom
UPDATE 3 (19.50 h CEST):
Police have released the five suspects in the five bombings at Silom intersection on Thursday night.
One of the suspects, Jaturon Noppakit, 36, was a red-shirt supporter of the anti-government United Front for Democracy against Dictatorship (UDD).
Mr Jaturon said he was travelling from Wongwian Yai to join the red-shirt protesters in Silom but insisted he was not involved with the bomb attacks.
The other four were supporters of the multi-coloured group who opposed the red-shirt's movement. They had digital cameras and video cameras containing footages of the soldiers working at Silom intersection.

UPDATE 2 (19.30 h CEST):
A series of grenade blasts that hit Bangkok's business district on Thursday killed at least three people, Deputy Prime Minister Suthep Thaugsuban told reporters. He also said the government had no plan to crack down on anti-government protesters in the area, because women and children are among them.

Deputy Prime Minister Suthep Thaugsuban said in a national television broadcast at 11.30pm that the grenades were fired from behind the monument of King Rama IV, at the entrance of Lumpini Park, where the red-shirts were gathering. "They were fired from the red-shirts' side," he said.
He told the pro-government group, who called themselves the Love Silom group, to retreat.
(...)After the explosions, the two rival groups clashed again about 10.45pm near the Dusit Hotel. Both sides were seen hurling bottles at each other. Security forces reportedly had a difficult time controlling the area, according to television reports.

This was the third night after the red shirt protestors have barricaded the intersection with bamboo fences, closing a road leading to the rally site. There have been standoffs between police, red shirts and pro-governments "no colors" protestors (while it is possible that man of them are yellow shirts in disguise) in the last few days at that very same spot. See Richard Barrow's map for detailed location.
Gregoire Glachant has video of the aftermath after the first blast. You can see one injured foreigner (probably Australian), also it shows a hole in the roof of the BTS Skytrain station.
