Israel girds for 'day of rage'

Gaza City (CNN) -- A day after Israeli security forces killed at least two protesters amid a frenzied eruption of anger over the fatal shelling of a United Nations school, Palestinian leaders called for a "day of rage" Friday in the West Bank.

The call for a massive follow-up to what were already some of the largest West Bank protests in years comes as diplomats scrambled to find cease-fire proposal that would satisfy mortal enemies Israel and Hamas and end more than two weeks of violence that has claimed more than 800 lives, most of them civilians.

Israeli police posted additional officers in Jerusalem ahead of the protests, spokesman Micky Rosenfeld said on Twitter. Police had deployed between 3,000 and 4,000 officers to prepare for expected violence, the Jerusalem Post newspaper reported.

Meanwhile, Secretary of State John Kerry was meeting with U.N. Secretary General Ban Ki-moon and Egyptian Foreign Minister Sameh Shukri Friday, and the Israeli Security Cabinet was meeting in closed session. But it was unclear if a deal to at least temporarily end the violence was near, or that Hamas would accept it.
