After newly elected mayor is beheaded in Mexico, others ask federal authorities for protection

Four mayors in Mexico have asked federal authorities for protection after a colleague was beheaded last week in the southern state of Guerrero, officials said Tuesday.

Mayor Alejandro Arcos had been sworn into office less than a week before he was murdered.

Federal Public Safety Secretary Omar Garcia Harfuch said four mayors requested protection on Monday, a day after Arcos' remains were found. The requests came from Guerrero and another violence-plagued state, Guanajuato.
