VIDEO: Is Egypt's Sinai peninsula slipping into civil war?

Egypt's northern Sinai is a desert region of frequent lawlessness where the Bedouin tribesmen who live have complained of being neglected and oppressed by the central government. Tim Whewell went to find out if anything has changed since Egypt's revolution.

"This is me with my new Kalashnikov," the young water engineer tells me as we sit by a hotel pool in El-Arish on Egypt's north Sinai coast, clicking through snapshots on his mobile phone.

"Before the revolution I never needed one, but now I do. To protect my family. It's getting much more dangerous here."
