Dozens of tunnels had been destroyed since last August following the killing of 16 Egyptian soldiers in a militant attack near the Gaza fence.

Cairo said some of the gunmen had crossed into Egypt via the tunnels - a charge denied by Palestinians - and ordered an immediate crackdown.

The move surprised and angered Gaza's rulers, the Islamist group Hamas, which had hoped for much better ties with Cairo following the election last year of Egyptian President Mohamed Mursi, an Islamist who is ideologically close to Hamas.
