Panetta tries to repair strained relations with Pakistan

Islamabad, Pakistan (CNN) -- In Pakistan to repair damaged relations, CIA Director Leon Panetta urged top officials to step up efforts to hunt militants operating within its borders as the United States reduced troop levels in the south Asian

nation at the request of Islamabad.

Between 200 and 300 U.S. military personnel remain in Pakistan, said a U.S. military spokesman, who asked not to be identified. It's not known what the previous number was but an official U.S. statement said the reduction was in line with a request from the Pakistani government.

"We recently received a written request from the Government of Pakistan to reduce the number of U.S. military personnel here, and we have nearly completed that reduction," said Navy Vice Adm. Michael LeFever, a U.S. defense representative in Pakistan.

Pakistan's military chief Gen. Ashfaq Parvez Kayani said the United States "has drastically cut down" troop strength in Pakistan.

Panetta met with the chiefs of Pakistan's military and top spy agency Friday to discuss U.S. partnership with Pakistan, strained by disputes about how to pursue counter-terrorism efforts.

Panetta's unannounced visit was the latest in a series of such visits by U.S. officials -- among them, Secretary of State Hillary Clinton, Chairman of the Joint Chiefs of Staff Adm. Mike Mullen and Sen. John Kerry -- in efforts to smooth things over after Osama bin Laden was killed in a Navy SEALs raid in early May.

Panetta insisted that Pakistan launch a military operation in North Waziristan, a rugged mountainous region rife with militants, according to a senior Pakistani official who asked to remain anonymous because he is not authorized to speak to the media.

Kayani agreed with Panetta in principle but told the incoming defense secretary that Pakistani troops are already stretched thin.

Panetta and his Pakistani counterparts agreed to form a joint intelligence team to track militant targets inside Pakistan.

U.S. officials believe Pakistan is not doing enough to go after al Qaeda and other extremists, while the Pakistanis are upset with what they consider to be unilateral steps taken by the United States within their borders.

Washington did not give advance notice to Pakistani officials about the raid on bin Laden's compound in Abbottabad.

At his confirmation hearing Thursday for defense secretary, Panetta, described the U.S. relationship with Pakistan as "difficult" but "critical."

While Pakistan has proven to be a safe haven for extremists, a positive relationship with authorities in Islamabad is vital to the mission in Afghanistan, he said.

Afghan CIA bomber 'was courted as potential informant'

The suicide bomber who killed seven CIA agents in Afghanistan had been courted by the US as a possible informant, US intelligence sources have said.

They said he had not undergone the usual full body search before entering the base in Khost province, and so was able to smuggle in an explosive belt.

The attack was the worst against US intelligence officials since the US embassy in Beirut was bombed in 1983.

US President Barack Obama has praised the work of those killed in a letter.

Paying tribute to the fallen, Mr Obama said those killed were "part of a long line of patriots who have made great sacrifices for their fellow citizens, and for our way of life".

He told CIA employees in a letter that the victims had "taken great risks to protect our country" and that their sacrifices had "sometimes been unknown to your fellow citizens, your friends, and even your families".

Claim questioned

From the moment the bomb was detonated inside the base on Wednesday, says the BBC's Peter Greste in Kabul, questions were raised about how he managed to pass through security.

But now intelligence sources familiar with the investigation have said that CIA agents working from Forward Operating Base Chapman had been attempting to recruit the man as a potential informant.

A US official, and former CIA employee, said such people were often not required to go through full security checks in order to help gain their trust.

"When you're trying to build a rapport and literally ask them to risk [their lives] for you, you've got a lot to do to build their trust," he told the Associated Press news agency.

The Taliban have said one of their members carried out the attack.

Spokesman Zabiullah Mujahid told the BBC the Khost bomber was wearing an army uniform when he managed to breach security at the base, detonating his explosives belt in the gym.

However, this claim was denied by the Afghan defence ministry.

"This is the Taliban talking and nothing the Taliban says should be believed," said ministry spokesman Zahir Azimi.

Neither the names of the CIA officials killed nor the details of their work have been released because of the sensitivity of US operations, the agency said.

But the head of the base - who was reported to be a mother of three - was said to be among the dead.

As chief, she would have led intelligence-gathering operations in Khost, a hotbed of Taliban activity due to its proximity to Pakistan's lawless tribal region.

'Great sacrifice'

CIA Director Leon Panetta said six other agents had been injured in the attack.

He said the dead and injured had been "far from home and close to the enemy".

"We owe them our deepest gratitude, and we pledge to them and their families that we will never cease fighting for the cause to which they dedicated their lives - a safer America," he said.

The flags at the CIA headquarters in Langley, Virginia, are being flown at half-mast in honour of the dead.

Forward Operating Base Chapman, a former Soviet military base, is used not only by the CIA but also by provincial reconstruction teams, which include both soldiers and civilians.

The airfield is reportedly used for US drone attacks on suspected militants in neighbouring Pakistan.

A total of 90 CIA employees have been honoured for their deaths in the agency's service since its inception in 1947, according to the Washington Post newspaper.

Lithuania hosted secret CIA prisons

The CIA used at least two secret detention centres in Lithuania after the 11 September 2001 terror attacks on the US, a Lithuanian inquiry has found.

The report by a Lithuanian parliamentary committee says that in 2005 and 2006 CIA chartered planes were allowed to land in Lithuania.

It says that no Lithuanian officials were allowed near the aircraft, nor were they told who was on board.

Poland and Romania hosted similar CIA "black sites", media reports say.

In Lithuania, at least eight terror suspects were held at one centre on the outskirts of the capital Vilnius, the investigation found.

It was formerly a riding school and the suspects were reportedly held there between 2004 and 2005.

In August this year, US media reports claimed that Lithuania, Poland and Romania all hosted secret CIA interrogation centres.

But the parliamentary report appears to absolve Lithuania's political leaders of responsibility for any human rights violations that may have been committed by the CIA, the BBC's Rupert Wingfield-Hayes reports from Moscow.

It says even the president was unaware of exactly what the US intelligence service was doing.

Secret flights

The practice of "extraordinary rendition" and the long-suspected network of secret US detention facilities became among the most controversial aspects of the Bush administration's response to the 11 September attacks.

"Extraordinary rendition" is the tactic of capturing militant suspects in one country and transporting them to another without judicial oversight.

The BBC's defence and security correspondent Nick Childs says critics of the Bush administration saw it as a way of avoiding legal constraints and, in some cases, as they put it, "contracting out" torture - although American officials repeatedly denied the allegations.

The issue caused considerable strains between Washington and some of its key allies during President Bush's administration.

Many governments - not least the British - have been under pressure to disclose what they knew, Nick Childs says, and the tactics the Americans did or did not use, and how extensively, remain murky.

US officials have hinted at perhaps dozens of prisoners having been held in secret detention centres. A controversial European Parliament report, however, spoke of hundreds of so-called "rendition" flights.

So far, only one case has actually gone to trial. Recently an Italian court convicted more than 20 American agents in their absence of being involved in the abduction of a Muslim cleric from the streets of Milan in 2003.

US President Barack Obama announced early on that he was closing the foreign detention centre network.
