Tensions still high in Yemen's southern city of Aden Saudi-led warplanes bombed Yemen's main international airport and struck a renegade troop base in the capital, as Arab leaders vowed Sunday to pummel Iranian-backed rebels until they surrender. The Huthis and allied renegade military units have overrun much of the country and prompted Hadi to flee what had been his last remaining refuge in the main southern city Aden for Saudi Arabia. Dozens of people have been killed in clashes in Aden in recent days, but for some residents, life still goes on as normal. IMAGES AND SOUNDBITES
