I've got an idea! Let's conclude another treaty with these jihad groups! From [1] Xinhua, with thanks to Twostellas:

GAZA, Dec. 24 (Xinhua) -- A military wing of the Islamic Jihad (Holy War) movement launched two homemade rockets into southern Israel on Sunday morning despite a mutual cease-fire.

Saraya al-Quds Brigades claimed responsibility for firing two rockets into southern Israel's town of Sderot in a statement sent to reporters.

The rockets, fired from the northern Gaza Strip, came in response to "the Israeli violations and crimes committed everyday against the Palestinian people," said the statement.

Israel and the Palestinians agreed to a limited cease-fire in the Gaza Strip in late November following large-scale Israeli offensive.

However, Israel said the Palestinians have fired 51 rockets since the fragile truce took effect.
