Israel and Hamas agreed to a ceasefire deal, mediators said Wednesday, suggesting a pause may be coming soon in the devastating 15-month war in the Gaza Strip and raising the possibility of winding down the deadliest and most destructive fighting between the bitter enemies.

Not long after news broke about a cease-fire between Israel and Hamas following a 15-month war in Gaza, Israel's prime minister said a deal has not been reached.

Israeli Prime Minister Benjamin Netanyahu said late Wednesday that a ceasefire agreement with Hamas is still not complete and the final details are being worked out.
