Israeli Prime Minister Benjamin Netanyahu huddled late into the night Monday with his top ministers, a government source said, in what was understood to be a discussion about the Gaza operation.
Ministers in Netanyahu's inner circle -- the Forum of Nine -- were reportedly in talks over whether to agree to a ceasefire or expand the air and naval campaign into a ground operation.

Exiled Hamas leader Khaled Meshaal said that he would be pressing for an end to Israel's six-year-old blockade of Gaza as a precondition for any end to hostilities.
