Egypt deployment of armour in Sinai worries Israel

JERUSALEM, Aug 21 (Reuters) - Israel is concerned about the

deployment of Egyptian armour in a push against militants in the

neighbouring Sinai desert, saying the vehicles' entry wasn't

coordinated and is in violation of a 1979 peace treaty, an

Israeli official said on Monday.

Prime Minister Benjamin Netanyahu's government has not

lodged any formal protest preferring to try and resolve the

issue in quiet contacts including U.S. mediation, to avoid

worsening ties with Cairo already strained since Hosni Mubarak

was toppled by a popular revolt last year.

Egyptian security sources said this week they were preparing

to deploy aircraft and tanks in Sinai for the first time since a

1973 war with Israel, in a crackdown on Islamist militants

blamed for killing 16 border guards in an Aug.5 attack.

The U.S.-brokered 1979 peace treaty between Egypt and Israel

sets strict limits on military deployment in the Sinai.

The Israeli official, speaking to Reuters on condition of

anonymity, said Egypt had already sent "some" armoured vehicles

into the desert peninsula and that "Israel is bothered by the

entry of armoured vehicles in Sinai without coordination."

Egyptian television footage showed General Abdel Fattah

al-Sisi in Sinai addressing troops with tanks and heavy

equipment behind them. Other images from his visit broadcast by

Egypt's private ON TV showed a row of six tanks and five

armoured personnel carriers.

While Israel does not view the armour as a threat, the

official said, it wants to make sure it has a say over what

weaponry is deployed in the Sinai, which the peace treaty

intended as a demilitarised buffer zone.

"There is no precedent for armoured vehicles being deployed

in Sinai and certainly not without any coordination," he said.

Israel had urged Egypt to crack down on the militants, and

its security cabinet had approved an Egyptian request to use

attack helicopters in Sinai two weeks ago, after the Islamist

gunmen who attacked Egypt's security personnel also penetrated

Israel's border where they were killed.

But local media say Israel was worried coordination with

Egypt may suffer after a shakeup this month of Egypt's military,

including Islamist President Mohammed Mursi's dismissals of

officials Israel had long been in contact with.

In Cairo, Yasser Ali, a spokesman for Mursi, told Reuters

security measures in Sinai were "crucial" to Egypt's security.

An Egyptian military source told Reuters the Sinai security

sweep was in keeping with agreements reached with Israel a year

ago after eight Israelis died in a cross-border attack.

"We don't need to issue a daily report to Israel on the

operation as it is a matter of sovereignty and national

security," the source went on to say.
