John Kerry on Jerusalem attack: 'An act of pure terror'

At least four Israelis have been killed and eight injured when two men with a pistol, knives and axes attacked a West Jerusalem synagogue, according to police.

The attackers - Palestinians from East Jerusalem - were shot dead.

US Secretary of State John Kerry described the attack as "an act of pure terror" and urged Palestinian leaders to "take serious steps to restrain any kind of incitement".
