TRIPOLI, Libya (AP) — An explosion believed to have been caused by a bomb ripped through the military intelligence building in Libya’s eastern city of Benghazi at dawn Wednesday, causing damage to the structure and nearby homes but no injuries, a security official said.

The blast took place hours after gunmen stormed a jail in Benghazi and freed Islamist militant Salem al-Obeidi, the suspected killer of former rebel chief Abdel-Fattah Younis, according to a second security official.
