Officials have informed that gunmen killed one person at a wedding and kidnapped the groom and three others Friday at a Ciudad Juarez, Mexico, church before escaping.

CNN has reported that Chihuahua State Attorney General's Office spokesman Carlos Gonzalez said "It's unclear if this was gang or drug related."

Gonzalez further said that the shooting victim, described in his 20s, was shot in the back in the church's parking lot while running from the scene.

CNN also said that the groom, his brother, uncle and best man were kidnapped.

It was also noted by the report that in 2009, Ciudad Juarez had more than 2,600 drug-related deaths, and is alleged to be the most violent city in Mexico.

At least 870 people have been killed in Juarez so far this year, CNN has reported. (With Inputs from Agencies)
