CIUDAD JUAREZ, Mexico (AP) -- Officials say gunmen killed eight people at a drug and alcohol rehabilitation center in this border city.

Police say five others were wounded in the Wednesday night attack.

Police spokesman Cesar Ramirez says the people were listening to a pastor's sermon when the gunmen barged in and opened fire. He says police found 61 casings inside the center.

Ramirez says authorities are investigating and have made no arrests.

So far this year, officials say 787 people have been killed in Ciudad Juarez. Most of the killings have been drug-related.
