The legislature in the southern Mexican state of Guerrero has condemned the killing of a local mayoral candidate.

A statement late Friday from Guerrero's congress reported the killing of Ulises Fabian Quiroz, who was a candidate for mayor of Chilapa for the governing Institutional Revolutionary Party-Green party coalition. He was apparently shot Friday afternoon in the community of Atzacoaloya.

Guerrero has been the site of intense violence as multiple crime groups battle for control of drug cultivation and smuggling routes.

In September, 43 students from a teachers college disappeared in the Guerrero city of Iguala. The government says they were killed and incinerated by a drug gang collaborating with local police.

Supporters of the students' families have threatened to disrupt the June 7 elections.
