Security forces have freed four trade unions leaders abducted last week while on their way to a pro-constitution conference in the Red Sea city of Sharm El-Sheikh, General Federation of Trade Unions (GFTU) leader Mohamed Salem announced on Wednesday, Al-Ahram Arabic news website reported.
The federation announced last week that the General Union of Tourism leader, his deputy and secretary-general, and a labour ministry official had been taken hostage by unidentified armed assailants in Oyoun Moussa, a few miles from the Ahmed Hamdi tunnel that connects the Sinai Peninsula to the city of Suez.
They were on their way to Sharm El-Sheikh to attend a federation conference on the newly amended constitution.
Attacks on military and police targets surged in Sinai after Morsi was ousted in July.
