As the Egyptian government tightens its grip on domestic dissent, with new accusations leveled against deposed president Mohammed Morsi and 24 others, Israel and Egypt are quietly cooperating against Hamas in Gaza, The Times of Israel has learned.

Israel is allowing Egyptian Apache helicopters, active in northern Sinai, to circle above the Gaza Strip to convey a menacing message to the Hamas regime.

“Cooperation is growing tighter on the intelligence and operational level — in fact, on all military levels,” an Israeli official said on condition of anonymity due to the sensitivity of relations between Israel and Egypt.
