FEARS OF ELECTION DAY VIOLENCE

On Wednesday, an unidentified gunman opened fire on Kwanchai Praipana, a leader of Thailand's pro-government "red shirt" movement and a popular radio DJ.

The attack in Udon Thani, about 450 km (280 miles) northeast of Bangkok, was the most significant violence outside the Thai capital and illustrates the risk that the turbulence plaguing Bangkok could spread to other areas of Thailand.

Just a day before, he had warned of a nationwide fight if the military launched a coup, as widely feared.

Several governments have warned their nationals to avoid protest areas in Bangkok, among the world's most visited cities. China called on Thailand to "restore stability and order as soon as possible" through talks.

So far the military, which has been involved in 18 actual or attempted coups in the past 81 years, has kept out of the fray. Police are charged with enforcing the state of emergency and are under orders from Yingluck to handle protesters with restraint.

The emergency decree gives security agencies powers to detain suspects, impose a curfew and limit gatherings but some analysts said it was in part designed to give Yingluck legal protection if police step in.
