Officials say Egypt has deployed at least two helicopter gunships to the Sinai Peninsula in the hunt for militants behind the killing of 16 Egyptian soldiers at a checkpoint along the border with Israel. Suspected Islamists on Sunday evening attacked the Egyptian checkpoint, killed the troops, then stole two of their vehicles and burst through a security fence into Israel. Israeli aircraft then halted their assault. (AP Photo/Ariel Schalit)
