United Nations Secretary General Ban Ki-moon is due to arrive in Cairo on Monday, Nov 19 to weigh in on ceasefire efforts led by Egypt, Reuters reports.

"I am deeply saddened by the reported deaths of more than ten members of the Dalu family... (and) by the continuing firing of rockets against Israeli towns, which have killed several Israeli civilians," Ban said before leaving for Egypt.

"I strongly urge the parties to cooperate with all efforts led by Egypt to reach an immediate ceasefire," he added.

Nine members of the Dalu family - mostly women and children - were killed in the deadliest single attack since the beginning of the Israeli Operation Pillar of Defense.
