The group, which calls itself "Supporters of Islamic State of Iraq and Syria in Jerusalem," said in an online statement that the rockets it fired were aimed at a base occupied by Hamas’s armed wing, Izzadin Kassam


The attack comes amid mounting tensions between Hamas and Islamic State supporters in the Gaza Strip. Hamas arrested dozens of Salafi-jihadists who are affiliated with Islamic State, sources in the Gaza Strip said on Thursday. They said the arrests came following a series of bombings, which were reportedly carried out by the Salafi-jihadists in recent weeks.

Earlier this week, Hamas demolished a mosque frequented by Islamic State supporters in Deir el-Balah.

Hamas said that the mosque was a tent, and not a concrete structure, that was used by the extremists as a meeting venue.


Islamic State supporters have accused Hamas of waging a massive crackdown on their men. They issued a warning to Hamas to release the arrested men within 72 hours or face the repercussions of its actions.

The Salafi-jihadists also issued a warning to several top Hamas security officials in the Gaza Strip who are responsible for the crackdown.
