KABUL/WASHINGTON (Reuters) - The United States has intensified its drive against the Taliban-linked Haqqani network in an attempt to deal a lasting blow to the militants in Afghanistan before foreign combat forces depart this year, according to multiple U.S. officials.
The effort is taking on added urgency as the clock ticks down on a NATO combat mission in Afghanistan set to end in December, and as questions persist about whether Pakistan will take action against a group some U.S. officials believe is quietly supported by Pakistani intelligence.
The Obama administration has created a special new unit based in Kabul to coordinate efforts against the militant group, according to officials familiar with the matter. It was set up late last year, as part of a new strategy that involves multiple government agencies,
The unit, headed by a colonel and known in military parlance as a "fusion cell," brings together special forces, conventional forces, intelligence personnel, and some civilians to improve targeting of Haqqani members and to heighten the focus on the group, the officials said.
"Things are coming together in terms of the more comprehensive approach (against the Haqqanis). So, there's a lot of focus - there's a lot of energy behind it right now," said a U.S. defence official, who asked not to be identified.
It was not immediately clear whether the intensified focus on the Haqqanis has led to increased strikes on the group by the U.S. military or the CIA, which operates drones over Pakistan's tribal areas.
And it remains to be seen, this late in the NATO combat mission, how much damage the United States can inflict on the Haqqani network, which has proven resilient and uses Pakistan's tribal areas as a sanctuary.
The White House announced on Tuesday that President Barack Obama had ordered the Pentagon to prepare for a possible complete withdrawal of troops following Afghan President Hamid Karzai's refusal to sign a bilateral security pact.
The Haqqani network, which professes obedience to Taliban leader Mullah Omar, is believed to have been involved in some of the most audacious attacks of the Afghan war. These include assaults on hotels popular with foreigners, a bloody bombing of the Indian embassy in Kabul, a 2011 attack on the U.S. embassy, and several massive truck bombing attempts.
The group is also believed to be holding Bowe Bergdahl, the only known U.S. soldier missing in the war in Afghanistan.
Some U.S. lawmakers have complained that the Obama administration has dragged its feet in cracking down on the group after designating it a "foreign terrorist organization" in September 2012.
For example, it is unclear what diplomatic pressure Washington is putting on Islamabad to arrest individuals connected to the group, the lawmakers say.
Earlier this month, the U.S. Treasury froze the U.S. assets of three suspected militants linked to the Haqqanis, the Obama administration's first significant non-military move against the network since that 2012 designation.
The Pentagon has regarded the Haqqanis, seen as more skilled in attacks on foreign targets than other militants in Afghanistan, as an acute threat to its soldiers for years.
U.S. General Joe Dunford, who commands U.S. and allied forces in Afghanistan, told Defense Secretary Chuck Hagel of his concern about the state of the current U.S. effort against the group in a private letter last November, sources familiar with the matter said.
During a recent visit to Washington, Dunford told senior White House officials that the group was a top priority for him, the sources said.
'PERVASIVE, VIRULENT ENTITY'
Retired General John Allen, who commanded U.S. and NATO forces in Afghanistan from 2011-2013, said he initiated the request to designate the Haqqanis as a terrorist group in spring 2012 because military efforts alone were insufficient.
"My reason for doing that was that it is simply such a pervasive, virulent entity," Allen said in an interview.
"I was going to pressure them in every possible way inside the country, but I wanted them to feel it at a strategic level, to include attacking their finances, their assets - pressuring the entire nervous system of the Haqqanis."
Some Afghan and U.S. officials remain sceptical that the United States can seriously weaken militant groups such as the Haqqanis unless Pakistan cracks down on them from within or better controls its borders.
"Until the Pakistanis do something about the safe havens, that's going to be a problem. (Militants) can recruit and train and equip and prepare to launch in Pakistan," said Major General Stephen Townsend, who commands U.S. and NATO forces in eastern Afghanistan.
Townsend was speaking about the array of militants who infiltrate the border with Pakistan, not just the Haqqanis.
The former top U.S. military officer, Mike Mullen, told U.S. lawmakers in 2011 the Haqqanis were a "veritable arm" of the Pakistani intelligence agency ISI, which some U.S. officials believe seeks to strengthen the Taliban and its allies as a means of ensuring that archenemy India does not wield influence in Afghanistan. Pakistan denies such charges.
Founded by mujahideen leader Jalaluddin Haqqani, the group fought the 1980s Soviet occupation of Afghanistan with varying levels of support from Pakistani, Saudi and U.S. policy-makers.
In November, six members of Congress sent Obama a letter calling efforts against the Haqqanis "woefully insufficient", according to a copy of the letter obtained by Reuters.
"It is past time for the administration to comprehensively address the threat posed by the Haqqani network's deadly attacks," Mike Rogers, chairman of the House Intelligence Committee, told Reuters in a statement.
