Five officers from Israel's Mossad spy agency and three Egyptians will stand trial on Wednesday on charges of spying for the Jewish state, judicial sources said.

Egyptian prosecutors have accused the eight of espionage and supplying Israel with information impacting Egypt's national security, the sources said on Sunday.

The UAE summoned the Qatari ambassador on Sunday to protest against remarks made by a Muslim Brotherhood-linked cleric who slammed the Emirates for jailing Islamists, the foreign ministry said.

The summons was the first of its kind by a member of the six-nation Gulf Cooperation Council -- Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates -- against another GCC state since the bloc's formation in 1981.

An Egyptian jihadist group said Saturday that it fired a rocket at the Red Sea resort of Eilat which was intercepted by Israeli air defenses, its second in a fortnight.

Al-Qaida inspired Ansar Beit al-Maqdis (Partisans of Jerusalem), which is based just across the border from Israel in Egypt's restive Sinai Peninsula, threatened to follow Friday's foiled rocket fire with further attacks.

The brutal aftermath of the once euphoric Egyptian revolution is on stark display in a powerful New York exhibition that lays bare grief, death and shattered hopes.

Three years after protests first erupted across the Arab world, ultimately deposing autocratic rulers in Tunisia, Egypt, Libya and Yemen, the hopes of millions now lie stagnant or in tatters.

Deposed Egyptian leader Mohammed Morsi was back in court Saturday as his trial over the killing of protesters resumed, with the defense insisting he is still the legitimate president.

His trial is seen as a test for Egypt's military-installed authorities, who have come under fire for a heavy-handed crackdown on his Islamist supporters after he was forced out by the army last July.

Two roadside bombs exploded near a patrol car in Cairo Friday, and police fired tear gas at supporters of ousted President Mohammed Morsi in Alexandria, security officials in Egypt said.

One policeman was slightly wounded when his patrol car was hit by two roadside bombs in a Cairo suburb, the interior ministry said.

The U.N.'s human rights office on Friday expressed concern over a crackdown on the media by Egypt's military-backed rulers, spotlighting the treatment of reporters working for Al-Jazeera television.

"We are extremely concerned about the increasingly severe clampdown and physical attacks on media in Egypt, which is hampering their ability to operate freely," said Rupert Colville, spokesman for the U.N. high commissioner for human rights.

Egypt on Thursday warned users of social media such as Facebook and Twitter of arrests if they incited violence through their posts, saying there were being tracked.

The interior ministry said 10 members of the "terrorist (Muslim) Brotherhood" had already been arrested for such acts.

Unknown only two years ago, the head of Egypt's military, Abdel-Fattah el-Sissi, is riding on a wave of popular fervor that is almost certain to carry him to election as president. Many Egyptians now hail him as the nation's savior after he ousted the Islamists from power and as the only figure strong enough to lead.

Still, if he becomes president, el-Sissi runs enormous risks.

Egyptian prosecutors Wednesday referred to trial 20 journalists working for Al-Jazeera television, including four foreigners accused of "airing false news."

The Qatar-based news channel, which has incensed Egypt's new military-installed authorities by its coverage of their crackdown on the Muslim Brotherhood, said the charges are baseless and "silly."
