LONDON:– Oil prices fell further Tuesday as the crude supply glut overshadowed a diplomatic row between key producers Saudi Arabia and Iran. Tensions between the two major oil producers over Saudi Arabia's execution of a prominent Shiite cleric have erupted into a full-blown diplomatic crisis after Riyadh and its Sunni Arab allies cut or reduced ties with Iran, sparking global concern. But analysts said that the impact of geopolitical risks in the Middle East on the oil market is being cushioned by the oversupply and higher output from oil producers in other parts of the world.–AFP
