An Israeli police spokesman said border police shot and killed a 16-year old Arab girl in southern Israel Saturday after she began shooting at a border police base.
The teenager, identified as a Bedouin high school student, had been armed with a pistol.
Also Saturday, Palestinian medical workers said Israeli troops killed two Palestinian gunmen along the border of the Hamas-ruled Gaza Strip.
An Israeli military spokeswoman confirmed troops had shot at several gunmen in northern Gaza and hit two of them.
Palestinian rescue workers said they recovered two bodies at the scene.
The incident is the latest in a string of sporadic violence in Gaza. The clash follows a period of relative calm in the wake of cease-fires that Hamas and Israel declared in January, ending a three-week Israeli offensive in the impoverished territory.
