Egyptians building Gaza barrier come under fire

Egyptians building Gaza barrier come under fire Gaza City: Security officials say shots have been fired from Gaza at Egyptians installing an underground metal barrier meant to seal border smuggling tunnels.

Palestinian and Egyptian officials say the shots were fired this morning, but that no one was hurt. They spoke on condition of anonymity because they aren't allowed to speak to reporters.

This is the fourth shooting incident since workers began building the barrier several weeks ago. The construction tightens a blockade imposed on Gaza after the militant group Hamas seized power in 2007.

The barrier has also worsened relations between Egypt and Hamas, which relies on the tunnels to haul in most commercial goods, as well as weapons.
