TOPSHOTS Smoke is seen above people gathering outside a mosque on the site of a powerful explosion in the northern Lebanese city of Tripoli on August 23, 2013. Two powerful explosions killed several people: one rocked the city centre near the home of outgoing Prime Minister Najib Mikati, the second one struck near the port of the restive city with a Sunni Muslim majority. The explosions come a week after a suicide car bombing killed 27 people in a Beirut stronghold of the Lebanese Shiite movement Hezbollah, which is fighting alongside Assad's forces.
