Sudan forces attack S. Sudan

BENTIU, South Sudan - Sudanese armed forces launched an attack more than six miles inside South Sudan's border, an official said Sunday, days after the south announced it was pulling its troops from a disputed border town to avoid all-out war between the two countries.

Ground troops from Sudan launched three waves of attacks, said Maj. Gen. Mac Paul, deputy director of military intelligence for South Sudan.

He said it was the first major engagement between the two armies since South Sudan announced it would pull out from the contested border town of Heglig.

Paul said the attack was part of a "continuous provocation" from Sudan. Sudan's military spokesman and other government officials were not immediately available to comment on the attack. - AP

U.S. envoy hails Yemen's fight

SAN'A, Yemen - The U.S. ambassador to Yemen said Sunday that a recent military shake-up has improved the fight against al-Qaeda, which has taken advantage of internal turmoil to overrun parts of the country's south.
