Clash between insurgents and Yemen troops kills 3

SAN'A, Yemen — A Yemeni security official says insurgents have attacked a military checkpoint in the country's south. He says the ensuing firefight killed one of the attackers and two soldiers.
The official says the assault took place on Wednesday in the town of Jaar in the southern Abyan province.
The official blamed the attack on al-Qaida insurgents. He says clashes are continuing between insurgents and security forces in the area and that he expects casualties.
Yemen's weak central government is struggling with a growing threat from al-Qaida, which has stepped up attacks in the impoverished and largely lawless country.
