US intelligence officials have twice handed Islamabad tips about insurgent bomb-making factories, only to find them abandoned before Pakistani troops arrived, according to The Washington Post.
The vacated factories have led US officials to question whether the information had been mistakenly leaked in recent weeks or whether the insurgents had been directly warned by Pakistan's powerful Inter-Services Intelligence (ISI) agency, according to the report.
The Post said Pakistani officials were given surveillance video in mid-May that located two bomb-making plants in the remote tribal areas of North and South Waziristan.
But by the time Pakistani troops arrived on June 4, the sites had been vacated.
A senior Pakistani military official said the United States had shared information about weapons storage facilities as well, but these had also been found empty.
“There is a suspicion that perhaps there was a tip-off,” the official told the newspaper.
U.S. is trying to mend the relations with Pakistan after Bin-Laden killing but it seems Pakistan's ISI will not cooperate with it. So far 34,000 Pakistanis have died in different attacks, since May, bomb blasts have become more frequent as Talibans promised revenge attacks on Pakistan. Pakistanis and Afghans are dying almost daily with the bombs made in Pakistan.
