A heavy sandstorm swept across parts of the Middle East on Tuesday, killing two people and hospitalising hundreds in Lebanon and disrupting fighting and air strikes 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/Ammar Awad
