Mexico City, Sep 17 (EFE) At least 24 people have been killed in separate incidents in the northern Mexican border city of Ciudad Juarez, which has been plagued in a vicious inter-gang drug war in recent times, authorities have said.

According to the police, gunmen armed with assault rifles entered a drug rehabilitation center Tuesday night in the Papalote neighborhood and killed 10 people, including a woman, while those inside were celebrating the 199th anniversary of Mexico's independence.

Five people were killed at a car wash, five at a bar and the other four were also gunned down in similar attacks, Juarez police spokesman Jacinto Segura told EFE.

The attack on the Life Center is the second such attack in a month on a drug-rehab facility in Juarez. On Sep 2, 18 people were gunned down at the El Aliviane clinic, which housed 50 people.

The bodies of the nine men and the woman were found in different rooms in the building, the police spokesman said, adding that two people were also apparently wounded in the attack.
