CAIRO (AP) — Egyptian authorities on Tuesday charged two Israelis and two Egyptians with forming an espionage ring for Israel, the second such trial to be called for in a month.

Prosecutor General Hisham Barakat alleged that the two Israelis are Mossad officers, and that two Egyptians, including a woman, helped provide them with information. The Egyptians are in custody and authorities have issued arrest warrants for the Israelis, although prosecutors do not know their whereabouts.
