Six mortar shells fell in a remote area of eastern Saudi Arabia near the kingdom's borders with Iraq and Kuwait without causing damage, a border guard spokesman said Thursday. The spokesman, General Mohammed al-Ghamidi, said Saudi authorities were in "direct contact" with its neighbours to identify the source of the shelling. "Six mortar rounds fell Wednesday in an uninhabited area... in Hafr al-Batin in Eastern Province, and no damage was caused," the official SPA news agency quoted Ghamidi as saying.
