Inactive grenade prompts evacuation at Puerto Rico airport

Puerto Rico authorities say an inactive grenade has prompted a partial evacuation at the island's main airport.

Police report that a 17-year-old passenger was carrying the grenade in his backpack. It belonged to his father, who was once in the military.

Transportation Security Administration agents spotted it during an X-ray scan Friday and evacuated an area at Luis Munoz Marin airport near the capital, San Juan.

Airport operations have since returned to normal.
