Security heightened at US base after escape

Security has been tightened at a massive US military detention facility in Afghanistan, a US official said today, a day after the military revealed that one of four men who escaped in July was a suspected al-Qaida leader in Southeast Asia.

The escape of Omar al-Farouq and three others, whom the military earlier described as a “threat to the global war on terrorism,” was the first from the jail, where more than 500 suspected militants are held.
