Cairo: Egyptian security forces on Saturday launched a manhunt for two Sudanese suspects in a terror plot in the Sinai peninsula, security sources said.

Police have set up security checkpoints on Sinai's main roads and have set up additional roadblocks on back roads to search for the men who might be carrying explosives.

The suspects are thought to have entered Egypt over its southern border with Sudan.

Police believe the two men were travelling in a truck and were "resolved to carry out terror attacks against tourist establishments in Sinai," the source said.
