JERUSALEM, July 22 (Reuters) – Gunshots fired across the border from Egypt on Sunday hit an Israeli army bus but caused no casualties, a military spokeswoman said.
The attack, in the central sector of the porous desert frontier, may heighten Israeli fears of an erosion of security in the Egyptian Sinai given the political upheaval in Cairo.
A Sinai pipeline built to supply Israel and Jordan with gas was blown up in a separate incident on Sunday, the 15th such sabotage since the start of a popular revolt that toppled the U.S.-aligned Egyptian president Hosni Mubarak in February last year.
The MB is asserting its hold on Egypt, they are going to be fighting soon.
