Islamabad has started investigations into three to four of its army officers suspected of having links with an extremist group as part of a bid to quash any allegations that Pakistan is supporting Muslim militant activities.
The names of the officers or the militant organisation were not disclosed.
Islambad also denied Indian reports that at least 12 other army officers were also being investigated for links with suspected militant groups.
Neighbouring India has blamed Islamic
extremists backed by Pakistan for last Monday's bomb attacks in its financial
capital Mumbai.
