Twin Explosions Hit Thailand Protests

The attack took place on Sunday, hours after an anti-government activist was wounded when a gunman opened fire at protesters shortly before midnight on Saturday.

The Erawan Medical Center says the injured were taken to four different Bangkok hospitals.

It was not immediately clear what caused the explosions.

The protesters, who control several small patches of the city, are vying to overthrow Prime Minister Yingluck Shinawatra's government, Al Jazeera reported.

While the day-time protests have been largely calm in Bangkok, assaults have been reported nightly, including shooting attacks at protest venues and small explosives hurled at the homes of high-profile protest supporters.

Protesters also want to derail February 2 elections, called by Yingluck in a bid to quell the crisis.

On Friday, an explosive device hurled at a crowd of marching demonstrators in another part of Bangkok killed one man and wounded dozens of people.

Police said the blast was caused by a fragmentation grenade.

The Southeast Asian nation has been wracked by repeated bouts of unrest since the military ousted Yingluck's brother, former Prime Minister Thaksin Shinawatra, in 2006 amid charges of corruption and alleged disrespect for the monarchy, which he denies.

The coup touched off a societal schism that in broad terms pits the majority rural poor who back the Shinawatras against an urban-based elite establishment supported by the army and staunch royalists who see Yingluck's family as a corrupt threat to the traditional structures of power.

Yingluck's opponents, a minority that can no longer win at the polls, argue the Shinawatras are using their electoral majority to impose their will and subvert democracy.
