Israel has created a stir by eliminating the leaders of Hamas and Hezbollah in a single day. On one hand, Israel entered Iran and killed Hamas leader Haniyeh, while on the other hand, it took revenge by attacking Hezbollah’s bases in Lebanon and killing its leader Fouad Shukr. But this is not the first time that Israel has killed them on enemy soil. The killing of Hamas leader Ismail Haniyeh in Tehran on Wednesday morning has also been added to this list. Hamas has described the death of Haniyeh, the head of its political wing, as murder. Hamas has vowed to take revenge. This has fuelled the fire of the already ongoing war in the Middle East. However, Israel has not yet taken responsibility for this attack. Israel often denies its role in targeted killings across the country’s border. Israel has killed many enemies before Haniyeh.

Yahya Ayyash, 1996

Yahya Ayyash, a bomb maker for Hamas, was assassinated in Gaza in 1996 via a fake cellular phone. Ayyash, known as the Engineer, was possibly targeted by Israeli agents. Ayyash was believed to use suicide bombing as a weapon against Israel. Israel considered him the mastermind behind the terrorist attacks since 1992 that killed at least 60 people and injured hundreds, the Washington Post reported. Although no one claimed responsibility for Ayyash’s murder, Israel’s state radio was the first to report his death, citing Israeli sources.

Khaled Meshal, 1997

Khaled Meshaal is a Hamas leader who survived the 1997 Israeli invasion of Jordan. Meshaal left the West Bank after the Israeli takeover in 1967. He then moved to Kuwait and then to Jordan in 1991 and became an active member of Hamas. He was made head of Hamas’ political bureau in 1996. A year later, Israel’s foreign intelligence agency Mossad injected a lethal poison into Meshaal’s ear in an operation on a street in the Jordanian capital, Amman, near Prime Minister Benjamin Netanyahu. Meshaal was saved when Jordan’s King Hussein arrested the agents responsible and threatened to abrogate the peace agreement with Israel if Israel did not provide an antidote to the poison.

Sheikh Ahmad Yasin, 2004

Sheikh Ahmed Yassin, Hamas’ founder and spiritual leader, was killed in an Israeli helicopter attack in Gaza City in March 2004. Yassin, a wheelchair-bound Palestinian cleric, was among those who founded Hamas in 1987. Yassin spent many years of his life in Israeli prisons. In 1983, he was arrested by the Israeli army for allegedly forming an underground organization and possessing weapons. He was released two years later as part of a prisoner swap. He was arrested again in 1989 and sentenced to 40 years in prison for inciting violence and ordering the killing of an Israeli soldier. He was released in 1997 after Jordan’s King Hussein reached a truce with Israel. After Yassin’s death, Rantisi was declared his successor. However, less than a month later, Rantisi died in an Israeli airstrike.

Abdel Aziz Rantisi, 2004

An Israeli helicopter attack in April 2004 killed Abdel Aziz Rantisi and his two bodyguards in Gaza. Rantisi was Hamas’ top leader at the time. Rantisi took over after Yassin’s assassination in March. “Israel will regret this – there will be revenge,” Haniyeh told reporters in hospital at the time. “This blood will not be wasted. The fighting will not weaken our determination.”

Mahmoud al-Mabhouh, 2010

Mahmoud al-Mabhouh, a senior Hamas activist, was murdered in a Dubai hotel room in January 2010. Hamas officials blamed Israel for the killing and vowed revenge. Israeli officials did not comment at the time on such allegations. Mabhouh was one of the founders of the Izzedine al-Qassam Brigades, Hamas’s military wing, and was accused of involvement in the kidnapping and killing of two Israeli soldiers in 1989.
