Ahmed Jabari

Jabari was born to an activist family based in the Shuja'iyya district of Gaza City in 1960, that was forced to leave Hebron due to a family blood feud.

He graduated from Gaza's Islamic University with a degree in history.

In 1982, he was arrested by the Israeli authorities and imprisoned for 13 years.

In 1982, Jabari was arrested and imprisoned by Israeli authorities when he was a member of the secular Palestinian militant organization Fatah.

According to Al Arabiya, while serving 13 years in prison, he left Fatah and joined Hamas after meeting with some of the latter's founders who were also incarcerated at the time, namely Abd al-Aziz Rantissi, Nizar Rayyan and Salah Shehadeh.

In the middle of the 1990s, Jabari was directly involved in planning suicide bombings against Israeli citizens.

After his release, in 1995 Jabari began to act as a commander in the military wing of the Hamas.

In addition, he dealt with the movement's charitable organizations and was responsible for coordinating between the collection of money and military activities.

After being released he joined Fatah's Islamist rival Hamas' militant wing and was believed to have been involved in the bombing of a bus in Kfar Darom, following which he was arrested by the Preventive Security Force of the Palestinian Authority in 1998, being released the following year.

Then, due to his involvement with these military activities in the Gaza Strip, Jabari was arrested by the Preventive Security Force of the Palestinian Authority in October 1998 for his alleged role in the Kfar Darom bus attack.

He was released in late 1999.

After his release he became an assistant of Salah Shehadeh and Mohamed Aldahef, the commanders of the military wing, in charge with improvement of military actions.

Thus, he was part of Hamas's high-ranking military leadership during the first intifada and of the first Intifada cell.

In 2002, Jabari became the acting operational head of Hamas' military wing when Mohammad Deif was seriously wounded in an Israeli airstrike.

In this position Jabari was also a high-ranking official within Hamas' political leadership, as well as the founder of the Nur Association, which aimed to help "martyrs and prisoners."

On 26 September 2002, after an Israeli airstrike wounded Mohammed Deif, the leader of Hamas's principal armed wing, the Izz al-Din al-Qassam Brigades, Jabari became the commander and operational head of the military wing at the height of the Second Intifada (the armed Palestinian uprising against Israel from 2000 to 2007).

However, Deif remains its official head.

According to Hamas political leader Ayman Taha, since Jabari took over the al-Qassam Brigades' day-to-day operations, Hamas's armed wing became increasingly professional.

During the course of the Intifada, he directed several attacks against Israel, including suicide bombings, that resulted in the deaths of hundreds of Israeli civilians and soldiers.

On 17 August 2004, Jabari's eldest son Mohammed, his brother and three of his cousins were killed in an Israeli air strike against Jabari's home in Gaza in an assassination attempt against him.

He escaped the attack unhurt.

He stated in a 2005 interview with Reuters that "Jihad and resistance" were the "only ways to liberate the homeland, and not negotiation and bargains."

He was widely credited as the leading figure in the Hamas takeover of the Gaza Strip, and commanded the 2006 Hamas cross-border raid which resulted in the capture of Israeli soldier Gilad Shalit.

Under his command, along with chief logistics officer Mahmoud al-Mabhouh, Hamas developed its own military weapons capability significantly by acquiring longer-range guided missiles and rockets.

While at the Islamic University of Gaza, Jabari joined Fatah, a Palestinian organization that advocated for an armed struggle against Israel.

Jabari was in charge of overseeing the captivity of Gilad Shalit who was kidnapped by Palestinian militants in 2006 outside of the Gaza Strip; two other soldiers were killed.

According to the Israeli government, Jabari played a leading role in Hamas' takeover of the Gaza Strip from the Fatah-led Palestinian Authority in June 2007.

Jabari was the highest-level Hamas official killed in Gaza since the 2008 Gaza War.

During Israel's offensive Operation Cast Lead against the Gaza Strip in December 2008, Jabari's home was allegedly destroyed in an airstrike, but the circumstances surrounding the incident were unclear and inconclusive.

After long years of military activities in Hamas, Jabari became one of the influential leaders within the organization.

In September 2010, Jabari threatened to increase attacks against Israel to derail the Israeli-Palestinian peace negotiations: "With the power of faith, weapons and missiles, tunnels and commandos we will achieve victory for Palestine and we'll end the occupation in Gaza too."

When a prisoners-exchange was arranged handing back Shalit to Israel in return for 1,027 Palestinian prisoners in October 2011, Jabari personally escorted Shalit to the Rafah Crossing with Egypt, making a rare public appearance.

Abu Hudaifa, a close confidante, noted that Jabari "followed the mission until the end in minute detail by himself."

In an interview with Al Hayat newspaper, Jabari confirmed that most of the 477 prisoners released in the first part of the prisoner exchange were collectively responsible for the deaths of 569 Israelis.

Ahmed al-Jabari (أحمد الجعبري; 1960November 14, 2012; also known as Abu Mohammad) was a senior leader and second-in-command of the military wing of Hamas, the Izz ad-Din al-Qassam Brigades.

The Israeli Air Force and Shin Bet conducted a targeted precision air strike on 14 November 2012, a part of Operation Pillar of Defense, killing Jabari while he was travelling in a car.

The decision to liquidate him, according to Haaretz analyst Reuven Pedatzur, arose from a decision by Israeli military to attack Hamas rather than seek a ceasefire.

In April 2012, Jabari was elected to the political bureau of Hamas.

Jabari was also instrumental in enforcing ceasefires from the Palestinian side, which included restricting rival militants groups from firing rockets and missiles.

In addition to his activities given above, Jabari served as a member of the group's political leadership.
