GAZA (Reuters) - An Egyptian military helicopter briefly crossed into Israeli-controlled airspace over the Gaza Strip on Friday, in a possible sign of increased security jitters a week after Egypt's army toppled President Mohamed Mursi.
Security sources in Egypt and Israel both described the flyover as a navigational error, but it came shortly after militants killed an Egyptian policeman and wounded a second in an attack on checkpoints in the lawless Sinai Peninsula across the border from the Palestinian Gaza Strip.
