A computer programmer, startled by a helicopter clattering above his quiet Pakistani town in the early hours of the morning Monday, did what any social-media addict would do: he began sending messages to the social networking site Twitter.   
With his tweets, 33-year-old Sohaib Athar, who moved to the sleepy town of Abbottabad to escape the big city, became in his own words "the guy who liveblogged the Osama raid without knowing it. " 
Soon the sole helicopter multiplied into several and gunfire and explosions rocked the air above the town, and Athar's tweets quickly garnered tens of thousands of followers as he apparently became the first in the world to describe the U. S.  operation to kill one of the world's most wanted militants.   
Athar did not respond to an Associated Press request for comment — he explained in another tweet that a filter he set up to stop his email box from flooding could be culling out requests for interviews.  He was up to more 70,000 followers by Monday evening.   
"I apologize for reporting the operation 'unwittingly/unknowingly' — had I known about it, I would have tweeted about it 'wittingly' I swear," he tweeted after realizing what he had witnessed.   
Later, he gave an interview to Al-Jazeera's English-language news network via Skype as he sat in a cafe.  When asked if he was scared, he said that he's from Lahore, "so I've had my share of bomb blasts. " 
His first tweet Monday was innocuous: "Helicopter hovering above Abbottabad at 1AM (is a rare event). " 
The noise alarmed Athar, who had moved to the upscale area of Abbottabad to get away from city life after his wife and child were badly injured in a car accident in the sprawling city of Lahore, according to his blog in July.   
Nestled in the mountains around 60 miles (95 kilometers) northeast of the capital, Abbottabad is a quiet, leafy town featuring a military academy, the barracks for three army regiments and even its own golf course.
