Umm Usama - the wife of the martyr Jamal al-Zibdeh - says that one day he came to her to tell her the path he would take with the resistance, and he left her the choice, so she chose without hesitation to support and support him, and to accompany him on the "path of jihad and resistance."

With a smiling face, Umm Osama received Al-Jazeera Net for a few minutes in a mourning pavilion filled with those she described as well-wishers, not mourners.

Assassination attempt

In the second war in 2012, Israel attempted and failed to assassinate al-Zebdeh. For many, the assassination attempt was a surprise, and was not linked at the time to his military value that emerged after his assassination as an official in charge of the Military Industrialization Department of the Qassam Brigades, and the development of the missile and drone program.

And Hebrew media, citing the Israeli Internal Security Agency, reported that Zebdeh was the most prominent research and development expert in Hamas.

Missile arsenal

The war on Gaza revealed a significant and remarkable development in Hamas' missile capabilities, with the introduction of its military arm - the Qassam Brigades - new types of missiles, with greater range and the ability to carry explosive warheads with high destructive power.

Hamas - mainly and as the largest faction in the "common room" of the resistance factions - has demonstrated a tangible ability to maintain the launch of more than 4,000 rockets over 11 days of the war, on a daily basis, with different ranges and high destructive capabilities.

The "Ayyash 250" missile was the latest missile that was discovered by the Al-Qassam Brigades and brought into service during the war. It bears the name of Yahya Ayyash - one of its most prominent leaders - who was assassinated by Israel in 1995, and has a range of 250 km, with a great destructive capacity.

The Zebda family is proud of Israel's accusations that Dr. Jamal was one of the most prominent officials responsible for developing this missile system.
