BANGKOK (AP) — Supporters of Thailand’s embattled government warned the country’s judiciary and senators against any attempt to install an unelected prime minister, saying it would be a disaster for the nation that could spark civil war.

Jatuporn Prompan, who heads the pro-government Red Shirt movement, made the comment during a rally Saturday on the western edge of Bangkok that was held three days after Prime Minister Yingluck Shinawatra was ousted in a controversial ruling by the Constitutional Court.
