A heavy sandstorm swept across parts of the Middle East on Tuesday, hospitalising scores of people in Lebanon and disrupting air strikes and fighting in neighbouring Syria. Clouds of dust also engulfed Israel, Jordan and Cyprus where aircraft were diverted to Paphos from Larnaca airport as visibility fell to 500 metres. REUTERS/Ali Hashisho
