UPDATE 1325 GMT: Pakistan's Geo News has posted that Saleem Shahzad's car has been found with an unidentified dead body and the journalist's identity.
Geo TV is now reporting that the http://www.twitter.com/AleemMaqbool">body is that of Shahzad and it bears marks of torture.
Sources on Twitter are reporting that Shahzad's brother-in-law has identified the body.
Last Friday, Syed Saleem Shahzad published the first part of a two-part special on a recent attack by insurgents on a Pakistani naval base. The article claimed that Al Qa'eda had infiltrated the base through links with several naval officers and that the assault followed the breakdown of talks to release those officers after they were detained.
On Sunday afternoon, Shahzad disappeared as he was en route to the studios of Dunya News to discuss the article. He is believed to have been abducted in Islamabad by agents of Pakistan's Inter Services Intelligence. No one has heard from him since, although Human Rights Watch claims it has confirmation that Shahzad has been detained by the ISI.
Shahzad's offending article:
Al-Qaeda carried out the brazen attack on PNS Mehran naval air station in Karachi on May 22 after talks failed between the navy and al-Qaeda over the release of naval officials arrested on suspicion of al-Qaeda links, an Asia Times Online investigation reveals.
Pakistani security forces battled for 15 hours to clear the naval base after it had been stormed by a handful of well-armed militants.
At least 10 people were killed and two United States-made P3-C Orion surveillance and anti-submarine aircraft worth US$36 million each were destroyed before some of the attackers escaped through a cordon of thousands of armed forces.
An official statement placed the number of militants at six, with four killed and two escaping. Unofficial sources, though, claim there were 10 militants with six getting free. Asia Times Online contacts confirm that the attackers were from Ilyas Kashmiri's 313 Brigade, the operational arm of al-Qaeda.
Three attacks on navy buses in which at least nine people were killed last month were warning shots for navy officials to accept al-Qaeda's demands over the detained suspects.
The May 2 killing in Pakistan of Osama bin Laden spurred al-Qaeda groups into developing a consensus for the attack in Karachi, in part as revenge for the death of their leader and also to deal a blow to Pakistan's surveillance capacity against the Indian navy.
The deeper underlying motive, though, was a reaction to massive internal crackdowns on al-Qaeda affiliates within the navy.
Volcano of militancy
Several weeks ago, naval intelligence traced an al-Qaeda cell operating inside several navy bases in Karachi, the country's largest city and key port.
"Islamic sentiments are common in the armed forces," a senior navy official told Asia Times Online on the condition of anonymity as he is not authorized to speak to the media.
"We never felt threatened by that. All armed forces around the world, whether American, British or Indian, take some inspiration from religion to motivate their cadre against the enemy. Pakistan came into existence on the two-nation theory that Hindus and Muslims are two separate nations and therefore no one can separate Islam and Islamic sentiment from the armed forces of Pakistan," the official said.
"Nonetheless, we observed an uneasy grouping on different naval bases in Karachi. While nobody can obstruct armed forces personnel for rendering religious rituals or studying Islam, the grouping [we observed] was against the discipline of the armed forces. That was the beginning of an intelligence operation in the navy to check for unscrupulous activities."
The official explained the grouping was against the leadership of the armed forces and opposed to its nexus with the United States against Islamic militancy. When some messages were intercepted hinting at attacks on visiting American officials, intelligence had good reason to take action and after careful evaluation at least 10 people - mostly from the lower cadre - were arrested in a series of operations.
"That was the beginning of huge trouble," the official said.
Those arrested were held in a naval intelligence office behind the chief minister's residence in Karachi, but before proper interrogation could begin, the in-charge of the investigation received direct threats from militants who made it clear they knew where the men were being detained.
The detainees were promptly moved to a safer location, but the threats continued. Officials involved in the case believe the militants feared interrogation would lead to the arrest of more of their loyalists in the navy. The militants therefore made it clear that if those detained were not released, naval installations would be attacked.
