Suicide Bomber Kills Three Yemeni Soldiers SANAA (Reuters) - At least three Yemeni soldiers were killed on Tuesday when a suicide bomber rammed a vehicle laden with explosives at a checkpoint in southern Yemen, a police source said. The source told Reuters that at least four other soldiers were wounded in the attack outside the city of al-Bayda, in the al-Bayda province. No one has claimed responsibility for the attack, but Islamist militants linked to al Qaeda have exploited months of pro-democracy protests last year to grab swathes of territory in the southern part of the country. Militants from Ansar al-Sharia earlier this month launched a wave of coordinated attacks on government forces outside Zinjibar, capital of the province of Abyan, killing at least 110 soldiers. At least 59 militants were killed in a series of air strikes on militant outposts last week. Reporting by Mohammed Ghobari, writing by Sami Aboudi
