(Reuters) – At least three children were killed and 20 people wounded by a car bomb in the Libyan city of Benghazi on Monday, witnesses and a medical official said. A Reuters reporter saw billowing smoke and flames at the site of the explosion near the city’s Jala hospital, which witnesses said had been caused by a car bomb. A hospital official said the bodies of three children had been received. Benghazi has been the scene of fighting between the Libyan National Army (LNA) and Islamist-led opponents for more than two years. The LNA has made major advances in this year, but faces pockets of resistance in parts of the city.
