In a Middle East that is already fraught with tension, this is another dangerous moment.
Israel’s most widespread military operation in the occupied West Bank is ongoing with reports in the last hour of fierce gun battles between Israeli forces and Palestinian militants in the northern city of Jenin.
Israel has called it a "counter-terrorism operation", but civilians are being caught up in the violence.
As night falls, many in the region will be watching nervously to see where it goes from here.
