CAIRO -- A drive-by shooting killed four Egyptian police near a famed historic site on the outskirts of Cairo on Saturday and a military helicopter crashed due to a "sudden technical failure" northeast of the capital, officials said.
Masked gunmen on a motorcycle opened fire on a security checkpoint near Saqqara, said police Maj. Gen. Khaled Shalaby. The tourist site is home to the 4,600-year-old Step Pyramid. No one immediately claimed the attack.
