Shots fired from Egypt at Israeli troops, none hurt

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.

Mubarak was succeeded by Mohamed Mursi of the Muslim

Brotherhood, which is ideologically hostile to the Jewish state

and linked to the Hamas Islamists who run the Gaza Strip, a

Palestinian territory that also abuts Sinai.

Israeli Prime Minister Benjamin Netanyahu said in April that

Sinai was becoming a lawless "Wild West," but his government has

since signalled more confidence in the new Egyptian government's

ability to restore order.

Last month, gunmen whom the Israeli military said crossed

into Israel from Sinai fired on Israelis building a barrier on

the border, killing one worker before soldiers shot dead two of

the attackers.

An Egyptian security source said officials were still

investigating what he described as "Israel's claims that a

sniper opened fire from inside the Egyptian lands near Egypt's

borders with Israel towards a bus carrying Israeli passengers."
