"Gas has resumed flowing at commercial levels," an Israeli energy official told Reuters on Friday, 10 June.

Gas flow was stopped for more than a month following explosions on the Egyptian side of the pipeline in the wake of political turmoil and the ouster of former president Hosni Mubarak.

Experimental testing on the pumping of gas to Israel and Jordan began on Tuesday after repairs were made to the pipeline that was attacked in April, Ampal-American Israel Corp said.

Egypt said in April it would review its gas contracts with other states including Israel and Jordan. The exports have long been a contentious issue in Egypt, with some accusing Mubarak's government of selling gas too cheaply to Israel.

Israel receives up to 45 per cent of its gas from Egypt under a 20-year deal signed in 2005. The two countries signed a peace deal in 1979.
