Egypt confirmed on Tuesday that 30 Islamic Jihad operatives have entered the Gaza Strip through the Rafah crossing, Palestinian news agency Ma'an reported.
According to the report, most of those who returned to Gaza are terrorists belonging to the Al Quds Brigades, the military wing of the group.
The operatives were injured during the Intifada and were abroad for medical treatment.
Official sources of the brigades denied the reports, although the Islamic Jihad confirmed that one man did return to Gaza with full cooperation of the Egyptians.
Last week, Egypt allowed 80 more Hamas operatives to return to Gaza.
