Gunmen kill 1, wound 4 protesters in attack on anti-government demonstrators in Thai capital

Gunmen killed one person and wounded four Tuesday, in another attack on anti-government protesters in Thailand's long political crisis, authorities said.

The shots were fired in midafternoon at a bus and a flatbed truck carrying demonstrators to their encampment in central Bangkok after they had protested at a complex of government offices just north of the city.

The website for Erawan emergency services said three men and two women were shot and one of the men died at a hospital.

The women were on a bus and the men were guards for the protesters who were on a sound truck, said Nasser Yeemah, who heads the self-described guards for the Student and People's Network for the Reform of Thailand protest group. He said he suspected the shots were fired from a tall building alongside the expressway where the vehicles were travelling.

The student network is a militant faction of the People's Democratic Reform Committee, which has been seeking to have Prime Minister Yingluck Shinawatra resign to make way for an interim appointed government to initiate anti-corruption reforms.

Police Maj. Gen. Anucha Romyanan confirmed the circumstances of the shooting and said it was not immediately known what type of weapon was used.

Protest-related violence has left 24 dead and hundreds hurt since November.
