He added, however: “If the ceasefire is violated, the State of Israel reserves the right to respond forcefully. “We will not allow any disruption in the lives of the citizens of the State of Israel.” Ziyad al-Nakhala, secretary general of Islamic Jihad, said: “If the occupation does not live up to what was agreed, we will consider the agreement invalid and continue the round of fighting without hesitation.” Islamic Jihad also said the truce would include the release of one of its leaders, Bassam al-Saadi.
