Israeli bulldozers have demolished large areas of the now virtually empty Jenin refugee camp and appear to be carving wide roadways through its once-crowded warren of alleyways, echoing tactics already employed in Gaza as troops prepare for a long-term stay.

Israeli tanks have moved into the occupied West Bank for the first time in decades in what Palestinian authorities call a “dangerous escalation.”

The Israel Defense Force confirmed Sunday that it has deployed tanks to the West Bank as it expands counter-terrorism operations in Jenin.
