BANGKOK, Feb. 2 -- Thailand's general election kicked off at 8 a.m. local time Sunday, amid concerns of possible violence and bloodshed due to disruption from anti-government protesters.

Sunday's voting will last till 3 p.m., with a total of 93,305 polling stations set up in 375 constituencies nationwide for 48.77 million eligible voters.

The election is confronted with a number of problems, though.

The Election Commission decided on Saturday night to cancel voting at all polling stations at the Lak Si district in Bangkok following clashes between pro-government "Red Shirts" and protesters, which left at least eight people injured. Fears of similar incidents run high.

Protest leader Suthep Thaugsuban has called a mass rally on Sunday to completely paralyze the capital and prevent people from casting their votes. He has been marching on Bangkok streets over the past days to mobile people to join in.

In addition, ballots delivery to several southern provinces has been blocked by protesters.

It remains to be seen whether the country will be able to go through with the election and how many voters will successfully cast ballots amid blockade.

Democrat Party leader Abhisit Vejjajiva earlier said he would not go to vote on Sunday, calling the election "unconstitutional."

But members of the Democrat Party, which has boycotted the election, are free to decide if they will cast ballots or not.
