World must end 'terrorist scourge': Kerry

The attack in Nice proves that the world must work faster to end the "terrorist scourge," US Secretary of State John Kerry said on Friday morning.

Speaking in Moscow, where he is meeting his Russian counterpart Sergei Lavrov, Kerry said that urgent action must be taken, declaring Syria an "incubator of terror".

Kerry is in Moscow for what he called "serious and frank discussions" about the war in Syria, in which Russia and the US are backing opposite sides.
