Gunmen opened fire into a bar in northern Puerto Rico and killed at least seven people, injuring 20 others, police said Sunday. A prosecutor said a battle over drug traffic might have prompted the attack. A 9-year-old girl and a pregnant woman who lost her eight-month-old fetus after being shot were among those seriously wounded, said police Col. Jose Morales. The justice department plans to file a murder charge for the death of the fetus, said prosecutor Wanda Vazquez, who is investigating the case.
