The Syndicate of Journalists mourned three judges who were shot dead Sinai earlier on Saturday.

The syndicate condemned the attack that left three others wounded.

The attack came hours after Cairo Criminal Court sentenced ousted president Mohamed Morsi along with other Muslim Brotherhood members to death over jailbreak and espionage charges.

Such acts will not undermine the Egyptian judiciary, the syndicate said, stressing that it will stand against the "black terrorism."

It offered condolences to the Egyptian people, the judicial institution and the Judges' Club.
