Lahore: Pakistani security officials have detained a former Navy commando and his brother in connection with the militant attack on a naval air base this month, intelligence officials and relatives said on Monday.
Last week`s attack on the PNS Mehran base in Karachi, the headquarters of Pakistan`s naval air wing, embarrassed the military and raised fresh doubts about its ability to protect its bases after a similar raid on the Army headquarters in the city of Rawalpindi in 2009.
Kamran Ahmed, who was sacked from the navy about 10 years ago, and his younger brother, Zaman, were picked up from the eastern city of Lahore on Friday, five days after the attack that killed at least 10 military personnel.
"They have been detained in connection with the naval base attack and are under interrogation," one intelligence official said, without giving details. It was not immediately clear why Kamran Ahmed had been sacked.
Imran Ahmed, another brother who was not arrested, said the two were taken away by intelligence officials on Friday. He gave no details.
The Pakistani Taliban, which is allied to al Qaeda, claimed responsibility for the attack on the Mehran base, but many analysts believe they had inside help.
A group of between four and six militants besieged the base for 16 hours and destroyed two P-3C Orion aircraft from the Unites States, crucial for Pakistan`s maritime surveillance capabilities.
Pakistan has faced a wave of assaults over the last few years, many of them claimed by the Pakistani Taliban 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 a Pakistani garrison town earlier this month.
The raid embarrassed the military, which has been unable to explain how the al Qaeda chief hid in the country for years or how the Americans could launch the attack deep inside their territory.
