Egypt's prime minister has asked for the revision off all contracts to supply gas abroad, including to Israel, the official news agency MENA reported on Wednesday.

Prime Minister Essam Sharraf "has directed the revision and review of all gas contracts Egypt agreed to with all countries, including Jordan and Israel," the news agency reported.

"The contracts are to be revisited so the gas "would be sold with deserved prices that achieve the highest returns for Egypt," it added.

Egypt supplies an estimated 40 per cent of Israel's gas in what was under ousted president Hosni Mubarak a highly controversial deal.
