A ceasefire agreement helped brokered by Egyptian officials was expected to go into effect between Israel and Hamas at 11:00 p.m. PST, a Hamas spokesperson told reporters, ending a week of bombings, airstrikes and rocket fire.

But an Israeli spokesman told CNN that a deal was not finalized.

"Until you're there, you're not there," he said.

A Hamas spokesperson later told BBC and CNN that the deal to be be announced was more a de-escalation of fighting -- a calming down -- rather than than "a truce." Still, the deal was expected to end fighting on Tuesday.

ABC reported that Israeli missiles were still striking Gaza early Tuesday Pacific time, or evening in Gaza. And Israel's missile defense system was still intercepting fire out of Gaza.

More than 125 Palestinians and three Israelis have been killed in the deadliest violence in the region in four years.

The agreement was reached hours before U.S. Secretary of State Hillary Clinton was scheduled to arrive in Israel.
