Sources confirmed to Ma'an that the PA's General Intelligence Services summoned Abdel Halim Ghannam to investigate the event.Ghannam was a prisoner in Israeli jails for more than 7 years. He was released 10 months ago, and has been summoned several times for interviews with the PA's GIS since.
Ghannam has a Facebook page showing lots of photos of his son Mohamed Morsi, who was born at the end of December. He makes no secret that he is a Hamas and Muslim Brotherhood supporter.
His mother complained bitterly about the detention, saying "Is it not enough for my son to spend years in the prisons of the occupation? My son has Irritable Bowel Syndrome and takes several medications, and we lived with the bitterness of detention time and again, is it not our right to live safe and secure lives like the rest of the people?"
