Mohammed Deif

The United States Department of State added Deif to its list of Specially Designated Global Terrorists on 8 September 2015.

In April 2015, it was reported in Israeli media citing intelligence sources, that Deif survived the assassination attempt.

Mohammed Deif (Arabic: محمّد ضيف ‎; born 1965 in Khan Younis), born Mohammed Diab Ibrahim al-Masri, is the chief of staff and supreme military commander of Izz ad-Din al-Qassam Brigades, the military wing of Hamas. He has been Israel’s 'most wanted’ man for the last 24 years since 1995 for his direct involvement in terrorist attacks such as the killings of IDF soldiers, suicide bombings and kidnappings. The last Israeli attempt to kill Deif was in an airstrike on 19 August 2014. Hamas denied that Deif was killed. Deif's wife, infant son, and daughter died in the attack.

On 19 August 2014, the Israeli air force conducted an airstrike on a house in the neighbourhood of Sheikh Radwan in Gaza City that killed Deif's 27-year-old wife Widad, 7-month-old son Ali, 3-year-old daughter Sara, and three civilians. Hamas denied that Deif was killed.

In December 2010, the Hamas movement marked the 23rd anniversary of its establishment with an official booklet entitled The Path of Glory (Darb al-ezza), which includes statements by Hamas military leaders alongside statistical and numerical data on military operations carried out against Israel.

In February 2006, some Israeli media argued that Deif would build an Al Qaeda network in the Gaza Strip since he did not support the approach of Hamas. This claim, however, was denied by the Izz ad-Din al-Qassam Brigades.

In the early morning hours of 12 July 2006, an Israeli F16 aircraft bombed a house in which high-level ranking Hamas leaders were meeting. Deif survived the blast, but severely injured his spine. After this event, Ahmed Jabari became the acting commander of Hamas military wing Izz ad-Din al-Qassam Brigades .

Deif became the supreme military commander of the Izz ad-Din al-Qassam Brigades after Israel assassinated Salah Shehade in July 2002. Israel holds him directly responsible for the murder of dozens of civilians in numerous suicide bombings since 1995, among them the Jaffa Road bus bombings in Jerusalem. He along with Nidal Fat'hi Rabah Farahat and Adnan al-Ghoul played a key role in the attacks perpetrated in Israel. Deif has been the top of Israel's most wanted list for over two decades.

He has survived five Israeli air strikes, which caused him serious injuries and handicaps. Despite initial reports of his death in an Israeli air strike on 27 September 2002, an Israeli intelligence official confirmed that he survived the attack. His senior assistant, Adnan al-Ghoul, was killed in an Israeli airstrike on 21 October 2004.

Dief joined Hamas in 1990 with the help of Yahya Ayyash and Adnan al-Ghoul his long time associates. In 1994, Deif was involved in the kidnappings and murders of IDF soldiers Shahar Simani, Aryeh Frankenthal and Nachshon Wachsman. He was personally responsible along with Yahya Ayyash behind the bus bombings in Jerusalem and Ashkelon, attacks that killed about 50 Israelis. Five suicide bombers he sent into Israel in March 2000 were killed by Yamam. After his release from PA prison in April 2001, he was involved in a 'wave of bombing attacks' that lasted several months during the second intifada.
