What do Military Planners Call This?

     The Israelis, who control most of the borders around Gaza, are not letting any Palestinians leave during the aerial bombing and artillery shelling.

     Is there a word for this? America did something similar in Fallujah in 2004, although America let women and children leave before the seige that cut off water and electricity.

     Is it called a Turkey Shoot? Shooting Fish in a Barrel? Inscribe and Conquer? I have to say, it doesn't seem very sportsmanlike.
