"Haqqani is the most virulent strain of the insurgency. It's the greatest risk of the force and, frankly, from a high-profile attack perspective, perhaps the greatest risk to the campaign," General Joseph Dunford, Commander of the US and NATO forces in Afghanistan, told reporters.
"The Haqqani network has been more active in some ways over the last few months. So, we have energised our efforts accordingly. I don't think there's anything that we're doing today that's different than what we were doing before, but it may be more focused," he said in response to a question.
"So as we've worked with our Afghan counterparts, we certainly have tried to make sure that we have a shared appreciation for the threat of Haqqani, in that not only are our operations focused on Haqqani, but our operations with the Afghans are focused on Haqqani. So that's really what that has been about," he said.
"When you look at Haqqani's high-profile attack threat streams, and you look at the consequences of those threat streams against what we're trying to accomplish right now, clearly mitigating the risk of the Haqqani network is one of my priorities as a commander," he said.
Dunford said the US would deal with Haqqani as a threat to the force.
"In other words, the viability of our mission in 2015 to go after al-Qaeda is, obviously, inextricably linked to our ability to protect the force. Haqqani will be, in my mind, remain one of the biggest threats to the force, but largely we will try to deal with Haqqani by, with and through our Afghan counterparts," he said.
