KARACHI, Pakistan (AP) — Hundreds of Pakistanis protesting an anti-Islam film broke through a barricade near the U.S. Consulate in the southern city of Karachi on Sunday, sparking clashes with police in which one demonstrator was killed and more than a dozen injured.

In a move that could escalate tensions around the Arab world, the leader of the Hezbollah militant group called for protests against the movie, saying protesters should not only ‘express our anger’ at U.S. embassies but urge leaders to act.
