An Al-Jazeera journalist on retrial in Egypt has sued his Qatari employer for $100 million, his lawyers said on Monday, claiming the satellite network was negligent and supported blacklisted Islamists.

Canadian Mohamed Fahmy and two other Al-Jazeera journalists were sentenced last year to up to 10 years in prison on charges of supporting the Muslim Brotherhood movement in its coverage of mass protests that led to the ouster of president Mohamed Morsi in July 2013.

A Palestinian truck driver in the southern Gaza Strip was seriously wounded on Monday by gunfire from Egypt, medics said.

"A 27-year-old driver who was working at the Kerem Shalom crossing was seriously wounded on Monday morning by shots which were fired from the Egyptian side of the border," health ministry spokesman Ashraf al-Qudra said.

Suspected militants set off three small bombs on Sunday outside the home of an Egyptian judge who sentenced Islamists to death, wounding four people and damaging the building, police said.

Judge Mutaz Khafagi, who had also sentenced Muslim Brotherhood leader Mohamed Badie to life in prison, was in his first-floor apartment in the suburban Cairo building but was not injured in the explosions, a police official said.

Militants shot dead three Egyptian policeman and a retired officer in separate attacks in the capital of North Sinai, security officials said on Saturday.

Egyptian authorities have seized share certificates belonging to former star national footballer Mohamed Aboutrika in a company he founded amid allegations it funded the blacklisted Muslim Brotherhood, judicial officials said Thursday.

President Abdel Fattah al-Sisi said Egypt had "rescued" 27 Ethiopians from war-torn Libya, as state television showed him greeting the group at Cairo airport on Thursday.

It was not immediately clear how the Ethiopians were rescued, but Sisi's office said the group flown in on an Egyptian plane was "liberated by Egyptian and Libyan security services".

An Egyptian court said Thursday it will decide on June 4 on a prosecution appeal against a lower court's ruling that dropped murder charges against ex-president Hosni Mubarak.

In November, a lower court dismissed murder charges against the former strongman over the deaths of some of the roughly 800 people killed during the 2011 uprising that removed him from office.

The Egyptian military Wednesday shot dead three Palestinian gunmen who infiltrated through a smuggling tunnel in the Sinai town of Rafah on the border with Gaza, security officials said.

One policeman was killed and five others wounded in clashes with supporters of Egypt's ousted Islamist president Mohamed Morsi in a Nile Delta city, police said on Wednesday.
