The Israeli army warned the government in war-wracked Syria it will "suffer the consequences" after four rockets crashed Thursday into the north of the Jewish state and the occupied Golan.

"This was the work of (Palestinian militant group) Islamic Jihad, an organisation financed and working for Iran, and we consider the Syrian government responsible for the firing and it will suffer the consequences," the army said in a statement.

The Israeli military and security sources said four rockets fired from the Syrian-held sector of the Golan struck the occupied part of the plateau as well as the Galilee region of northern Israel, causing fires but no casualties.
