Explosion at Bus Stop in Jerusalem

A bus has exploded in Jerusalem. The number of casualties is unknown, but there are reports that people are being carried away on stretchers. The explosion came from a bomb left in a bag at a bus stop near the main entrance to Jerusalem, shattering windows in nearby buildings. It appears to be the first bus bombing in several years and comes amid rising tensions between Hamas militants and Israel. The BBC’s Bethany Bell reports from Jerusalem.
