Israel kills Hamas founders Yassin and Rantissi (2004)
Israel killed Hamas founder Sheikh Ahmed Yassin with a helicopter missile strike outside a Gaza City mosque on March 22, 2004. Less than a month later, on April 17, Israel killed his successor Abdel Aziz al-Rantissi in a strike on his car. Hamas stopped publicly naming its political leader in Gaza for years afterward.
Hamas refused to name a public successor and moved its senior leadership underground. Rocket fire from Gaza intensified in the weeks after each killing.
The killings did not break Hamas. The group won the 2006 Palestinian elections and took full control of Gaza in 2007.
The 2004 decapitation showed that killing Hamas's top leaders can drive the group's command underground without ending its operational capacity. Hamas may again respond by simply hiding its next chief's identity.
