This page is subject to the extended confirmed restriction related to the Arab-Israeli conflict.The 2009 Hamas political violence took place in the Gaza Strip during and after the 2008–2009 Israel–Gaza conflict.

A series of violent acts, ranging from physical assaults, torture, and executions of Palestinians suspected of collaboration with the Israel Defense Forces, as well as members of the Fatah political party, occurred.

"[9] A report in the Qatar-based newspaper Al-Sharq quoted Moussa Abu Marzuk, a high-ranking Hamas official, as confirming that the organisation had killed known collaborators.

In addition, individuals in official uniform or masked persons opened fire on people's legs, severely beat others, imposed house arrests, and threatened to punish citizens along with their families if they would not comply.

In 2007, both parties engaged in a military conflict, in which Hamas won control over the Gaza Strip and forced Fatah into the West Bank.
