The pre-dawn attack follows weeks of protests demanding resignation of Prime Minister Yingluck Shinawatra, triggering bloody clashes between police and opposition demonstrators.

"All of them were shot around 03.30 a.m. near the gate number 4 of Government House," Bangkok Administration's Erawan Emergency Medical Services Centre said.

"The dead man is in his 30s. He was shot in the torso," a spokesman for the centre said. It was not clear who fired the shots.

The attacks came a day after an injured anti-government protester succumbed to gunshot wounds on Friday.

A police officer was killed and 143 people including protesters, journalists and policemen were injured after violence erupted at the Thai-Japanese Stadium on Thursday.

With one more death on Saturday, the toll has now risen to three in the latest bout of political violence in Thailand.

The protesters have been demanding Yingluck's resignation since mid-October. The protests began after her government tried to introduce an amnesty bill that would have paved the way for the return of her brother, controversial former premier Thaksin Shinawatra currently in self-exile in Dubai.

Yingluck called the snap polls, scheduled for February 2, after weeks of protests. But the demonstrators have dismissed the election, and the official opposition has refused to field candidates. Protesters have further rejected another offer by Yingluck to form a national reform council intended to run alongside her government.
