The official was responding to a media report in a local newspaper that Pakistan will launch a military offensive against Al-Qaeda and Taleban safe havens in the Afghan border regions.
"Humanitarian agencies operating in FATA and Khyber-Pakhtoonkhwa were given the heads up two weeks ago by the authorities of a possible displacement of up to 50,000 families,” he said, referring to the Federally Administered Tribal Areas and the northwest province.
A similar tip-off in 2009 preceded a military offensive in neighboring South Waziristan by about five months, he said.
Other aid agencies were not immediately available for comment.
The report In Pakistan’s The News newspaper comes just days after US Secretary of State Hillary Clinton reiterated a US demand to tackle sanctuaries for Al-Qaeda and the Taleban on the Afghan border.
An understanding for an offensive in North Waziristan, the main sanctuary for militants fighting in Afghanistan, was reached when Clinton and Chairman of the Joint Chiefs of Staff Adm. Mike Mullen visited Pakistan last week, the News reported.
The United States has long demanded that Pakistan attack the region to eliminate the Haqqani network, one of the deadliest Afghan militant factions fighting US troops in Afghanistan.
Pakistan has been reluctant to do so, but it has come under more pressure and its performance in fighting militancy is under scrutiny again after it was discovered that Osama Bin Laden had been living in the country.
The News quoted unidentified “highly placed sources” as saying Pakistan’s air force would soften militant targets under the “targeted military offensive” before ground operations were launched.
The newspaper cited the sources as saying that a strategy for action in North Waziristan had been drawn up some time ago and an “understanding for carrying out the operation was developed” during the Clinton visit.
The target of any North Waziristan operation would be the most violent factions of the Pakistani Taleban, which has strong ties to Al-Qaeda, the report said.
But the United States would almost certainly push for a move against Haqqani, too.
Pakistani officials were not immediately available for comment. A US Embassy official had no immediate comment.
The newspaper said a “joint operation” with allies had been discussed but no decision had been taken because of sensitivities.
“In case the two sides agreed to go for a joint action, it would be the first time in the present war (on militancy) that foreign boots will get a chance to be on Pakistani soil with the consent of the host country.”
That could be highly risky for Pakistan’s generals.
Some analysts say any joint US-Pakistani operation would subject the army to more public criticism in a country where anti-US feeling runs deep.
“The reaction could be even more vociferous, just because everybody is so suspicious — as well as dismissive — of American interference,” said Imtiaz Gul, author of “The Most Dangerous Place,” a book about Pakistan’s militant strongholds.
“People already feel so humiliated because of this Osama Bin Laden thing and now they will have another reason to react.”
But the South Asian nation, dependent on billions of dollars in US aid, is under more pressure than ever to show it is serious about tackling militancy. Attacking US enemies in North Waziristan may be one way of repairing ties with Washington which were badly damaged by the Bin Laden affair.
Pakistan maintains about 140,000 troops in the northwest, including about 34,000 in North Waziristan, but says they are too stretched fighting Pakistani Taleban insurgents in other parts of the region to tackle North Waziristan.
Aside from strategic concerns, an attack on the Haqqani network could further threaten Pakistan’s security as it faces a new wave of attacks by the Pakistani Taleban to avenge the killing of Bin Laden by US special forces on May 2.
Highlighting the dangers in North Waziristan, a blast at a restaurant in its main town Miranshah killed one wounded 12 people on Monday, government officials and residents said.
