Before the current war in Gaza, Mohammed Deif, leader of Hamas’ military wing, the Al-Qassam Brigades, was known only to his family and a few within Hamas.
His true appearance remained a mystery until Israel released his image late last year, marking it as the fourth depiction. Previous images ranged from a young man to a masked figure and a silhouette.
The latest shows him calmly alongside someone with gray hair, a light beard, and one eye.
Deif maintained a high level of secrecy in all his movements. Even when his mother passed away in January 2011, it was unclear if he attended her funeral.
There were rumors he did, unrecognized, while others claimed he never attended due to security concerns. Some even suggested he disguised himself as an elderly man to bid his mother farewell before disappearing.
Deif appears not to use modern technology and is not fond of making public appearances. Rarely does he release voice messages, such as when he announced the start of new battles with Israel, including the Oct.7 Al-Aqsa Flood attacks.
Even during the current war, Israel’s pursuit of Deif in every corner of Gaza has proven elusive until now, with the targeting in Khan Younis marking the first revealed attempt after over nine months of conflict.
In fact, Israel has sought Deif since the mid-1990s. Shimon Peres, then Prime Minister in 1996, requested Palestinian President Yasser Arafat to arrest him, only for Arafat to express surprise at the name, seemingly unaware of him.
Peres later admitted discovering Arafat protected, hid, and lied about him.
Profile Overview
Real Name: Mohammad Diab Ibrahim Al-Masri, known as Deif. Born in 1965 to a Palestinian refugee family from Al-Qubeiba, settled in Khan Younis refugee camp, southern Gaza.
Deif grew up in poverty, briefly leaving school to help support his family by working with his father in textiles and later starting a small poultry farm. He also worked as a driver before becoming a target of Israeli pursuit.
Known for his friendly demeanor and interest in theater, Deif joined Hamas in late 1987 through mosque connections. He completed his studies at the Islamic University of Gaza in 1988, earning a Bachelor’s degree in Science.
Arrested by Israel in 1989 without trial, he spent 16 months in prison accused of involvement in Hamas’ military wing. Upon release, he co-founded the Al-Qassam Brigades and played a significant role in operations against Israel throughout the 1990s.
