On the first anniversary of their disappearance in the Sinai en route to Cairo, Al-Jazeera Live TV has published a leaked photo from an Egyptian prison in Cairo of two of the four Palestinians who disappeared a year ago after masked gunmen attacked their bus a few hundred meters away from the Rafah Crossing.

Smoke rises after a house was blown up during a military operation by Egyptian security forces in the Egyptian city of Rafah near the border with southern Gaza Strip October 30, 2014, as Egypt began setting up a buffer zone along the border with the Hamas-run territory to prevent militant infiltration and arms smuggling following a wave of deadly attacks. The move, which is set to result in the demolition of hundreds of homes, comes after a suicide bombing in the Sinai Peninsula killed at least 30 soldiers last week.

Yasser Zanoun and Abdulkareem Abulibda appeared in the photo surrounded by semi-naked people who appeared to have suffered from lack of food and proper treatment.

Dozens of Palestinians organized a sit-in in front of the headquarters of the International Committee of the Red Cross in Gaza days ago and presented a letter to the ICRC asking for identifying the location of the men, and working on their release.

The families of the two Palestinians confirmed the identities of their children in the photo.

Hamas-Egypt relations have deteriorated following the military coup in Egypt in 2013 that resulted in ousting elected president, Mohammed Morsi, who shared ideological grounds with Hamas. The four Palestinians are members of Hamas’s military wing, Al-Qassam Brigades.
