The US is to designate the Pakistan-based militant Haqqani network as a
terrorist organisation, subjecting it to sanctions.
US Secretary of State Hillary Clinton said she had sent a report to Congress
saying the network met the criteria as a terror group.
She said the US would continue "diplomatic, military and intelligence
pressure on the network".
The US has long described the Haqqani group as a major threat.
The network - which has links to al-Qaeda and the Taliban - has carried out a
series of high-profile attacks against foreign troops in Afghanistan.
The designation will ban companies and individuals in the US from supporting
the group and freeze any US assets it may have.
State department officials said the formal designation would be made in the
coming days.
"Today, I have sent a report to Congress saying that the Haqqani network
meets the statutory criteria of the Immigration and Nationality Act (INA) for
designation as a Foreign Terrorist Organisation (FTO)," said Mrs Clinton, who is
currently attending an Apec (Asia-Pacific Economic Co-operation) summit in
Vladivostok, Russia.
"We also continue our robust campaign of diplomatic, military and
intelligence pressure on the network, demonstrating the United States's resolve
to degrade the organisation's ability to execute violent attacks."
Mrs Clinton added that she was taking the action "in the context of our
overall strategy in Afghanistan" following policy laid out by US President
Barack Obama when he visited Afghanistan in May.
The Pentagon said the Haqqani network "represents a significant threat to US
national security and we will continue our aggressive military action against
this threat".
"These new group designations will build on our efforts to degrade the
network's capacity to carry out attacks, including affecting fundraising
abilities, targeting them with our military and intelligence resources, and
pressing Pakistan to take action," said George Little, the acting Assistant
Secretary of Defence for Public Affairs.
Hostage
fears
In response to the US move, senior commanders of the Haqqani network told
Reuters news agency that the decision showed the US was not sincere about peace
efforts in Afghanistan.
They also said the move would "bring hardship" for US army sergeant Bowe
Bergdahl, 25, who has been held prisoner for more than three years.
The Haqqanis also hold numerous Western, Pakistani and Afghan hostages as
well as kidnap-for-ransom victims.
The US has been putting pressure on Pakistan to launch a ground offensive in
North Waziristan, where the Haqqanis are based, but Pakistan is reluctant.
The BBC's Jill McGivering says that any such offensive would probably be
focused on disrupting the Pakistani Taliban - an internal threat - and not on
attacking the Haqqanis, whose battleground is Afghanistan.
The US fears that Islamabad sees the Haqqanis as potential allies after
Nato's withdrawal from Afghanistan, she says.
Last year, US Admiral Mike Mullen, former head of the US military, said the
Haqqani network had become a "veritable arm" of Pakistan's Inter-Services
Intelligence (ISI) agency.
Analysts say this prompted suggestions that a designation against the
Haqqanis would indirectly be branding Pakistan a terrorist state.
In Washington, the White House has also been under political pressure from
Congress to add the Haqqanis to the country's terrorist blacklist.
Congress had set Mrs Clinton a deadline of this weekend to deliver her
report.
Meanwhile, the US has been disrupting the group, targeting leaders in drone
attacks.
Last month, an air strike in North Waziristan was reported to have killed a
key Haqqani commander, Badruddin Haqqani.
He had been described as a senior operational commander, masterminding and
directing attacks on high-profile targets.
Correspondents say he was also responsible for training camps and for
extorting funds from contractors.
