An Israeli security guard holds an electronic device at the Kerem Shalom crossing outside the southern Gaza Strip January 12, 2009. Israel said on Monday it was investigating how a night-vision security camera and other electronics ended up on humanitarian aid trucks bound for the war-torn Gaza Strip. The equipment was seized at the Kerem Shalom border crossing before entering the coastal enclave along with truckloads of food, medicine and other humanitarian goods, said defence official Peter Lerner.
