At least 70 Palestinians were killed in Israeli attacks in the occupied West Bank since the start of this year, the Health Ministry said on Monday. The victims included 10 children, one woman and two elderly people, the ministry added in a statement.

Prime Minister Benjamin Netanyahu said the assault on Jenin would be “extensive and significant,” as the military erected new checkpoints across the West Bank.

As Israel withdraws some of its troops from Gaza during a cease-fire there, it has turned attention to another Palestinian territory — in particular a city with a history of militant activity.
