Pakistan detains nuclear scientists again

Two retired Pakistani nuclear scientists, suspected of having links with Osama bin Laden have been detained again for questioning.

Authorities first took the pair into custody on October 23 and announced last week that they had been released.

However, army General Rashid Quereshi said the scientists, Sultan Bashir-ud-Din Mehmood and Abdul Majid, had been brought in for further interrogation. He declined to say why. Other officials said no charges had been filed.

The two men had worked for Pakistan's Atomic Energy Commission until their retirement in 1999. Both subsequently made frequent trips to Afghanistan and met bin Laden on two occasions, government officials have said.
