ISLAMABAD: Security forces on Tuesday arrested three suspects from F-8 sector near Navy Headquarters in Islamabad.
According to sources, the suspects were taking pictures of sensitive installations in the area.
The arrested men have been identified as Saeed Khan, Shehzad Khan and Akhtar Khan. Documents retrieved from them show that they belong to the Ibrahim Khel area of Peshawar.
Officials have also seized cameras and mobile phones from the three men and they have been shifted to an unknown location for further investigations.
Pakistan Navy had earlier come under attack when a group of between four and six militants besieged PNS Mehran airbase in Karachi for 16 hours and destroyed two P-3C Orion aircraft from the Unites States, crucial for Pakistan's maritime surveillance capabilities.
The Tehrik-i-Taliban Pakistan (TTP), which is allied to al Qaeda, claimed responsibility for the attack on the base, but many analysts believe they had inside help.
Pakistan has faced a wave of assaults over the last few years, many of them claimed by the TTP and other al Qaeda-linked militant groups.
In October 2009, a small group of militants attacked the Army's General Headquarters in Rawalpindi, taking 42 people hostage, including several officers. By the end of the day-long siege, nine gunmen, 11 soldiers and three hostages were dead.
The Taliban have stepped up attacks since the killing of Osama bin Laden in a US raid in Abbottabad.
