A shoot-on-sight curfew imposed in Katmandu to prevent riots and violent protests over the killing of 12 Nepalese workers in Iraq entered its third day Friday, as officials said they were trying to recover the hostages' bodies. The prime minister, meanwhile, ordered a probe into earlier mob attacks on a mosque, media offices and Middle Eastern and Pakistani airline offices in Nepal's capital. Tourists trickling into Katmandu were driven to their hotels in buses with armed escorts, and soldiers kept watch as city workers swept broken glass, burnt tires and pieces of broken furniture from the debris-littered streets. The lockdown on Katmandu also forced the cancellation of Friday prayers at the "Jame" mosque, which was ransacked on Wednesday after an angry mob received word that the Nepalese hostages had been killed. Troops guarded the mosque. Prime Minister Sher Bahadur Deuba visited the mosque Friday and ordered an investigation into the attack. "Those found guilty will be punished," Deuba said.
