In an interview Wednesday with The Associated Press, Marine Gen. John Allen said the “high-intensity” operation is focused on the Haqqani group, a militant network affiliated with the Taleban and Al-Qaeda.

Allen also says the transfer of security to Afghan forces is going to move faster than initially planned.

And he says roughly one-third of the 10,000 US troops President Barack Obama ordered withdrawn from Afghanistan this year will come from combat units.
