Military spokesman, Major General Athar Abbas said there was consensus between the army and CIA in taking action against Al-Qaeda and their supporters.
According to the military spokesman, the army was following Al-Qaeda operative Younis al-Mauritani since last October and he was captured in collaboration with the CIA this week.
He added that in the past, successful operation against terrorists had been conducted with the help of the CIA.
On Monday the army announced it had arrested a senior Al-Qaeda leader believed to have been responsible for planning attacks on the United States, Europe and Australia.
Younis al-Mauritani was picked up in the suburbs of Quetta along with two other high-ranking operatives after US and Pakistani spy agencies joined forces, according to the Pakistan army.
It named the two other senior operatives as Abdul Ghaffar al-Shami and Messara al-Shami.
The United States also praised the operation with a White House spokesman calling it an example of partnership between the two countries “which has taken many terrorists off the battlefield over the past decade”.
