Cairo - Egypt's prosecutor general has referred two Israelis and two Egyptians to trial over charges of forming an espionage ring for Israel.
The Tuesday decision from Hisham Barakat said two of the accused were Israeli Mossad officers and two were Egyptians, including a woman.
Earlier this month, a court in the Suez Canal city of Ismailiya began to hear the trial of eight people including five Israelis and three Egyptians on similar charges. The Israelis were tried in absentia.
The trials are taking place amid near-daily reports of plots in the media, with foreign parties regularly accused of conspiring with the Islamist Muslim Brotherhood group to destabilise Egypt.
The army-backed interim government has cracked down on the group following the 3 July ouster of Islamist president Mohammed Morsi, who is himself standing trial on a range of charges including conspiring with the Palestinian militant group Hamas.
