Commuter trains collide in Italy

At least 20 people are dead in Italy after two passenger trains collided head-on in the southern Puglia region, about 200 miles south-east of Rome. Rescue crews continue to search the rubble for survivors. The two small electrical trains are part of a network that serves mostly students and commuters traveling between Puglia and its surrounding towns. Officials don’t yet know what caused the two trains to be traveling in opposite directions on the single track near the town of Andria.
