The Thai government has blamed a deadly blast at an apartment complex near Bangkok on the anti-government Red Shirt movement.
Investigators suspect a bomb-maker caused the explosion accidentally. 


Authorities said the incident, which killed four people and injured nine, was linked to political unrest
The Thai government has stepped up security following a string of minor blasts in Bangkok, including one at a bus stop in July that killed a man, but it insists the latest bomb explosion will have little impact on tourism
Tourism and Sports Minister Chumpol Silpa-archa said foreign countries now have a good understanding of the country’s political situation and the government’s efforts to maintain law and order.
“They understand that the renewal of emergency decree in Bangkok and adjacent provinces was partly to ensure security for foreign tourists.
“Reports of bombings in the capital might have some psychological effect, but actually the number of foreign tourists visiting Thailand is increasing,†he said.
