At least seven Afghan soldiers have been killed in a roadside bomb blast in southeastern Afghanistan, with an army commander linking the attack to Taliban fighters.

 

Meanwhile, Mullah Dadullah, a Taliban military official, has told Al Jazeera in an exclusive interview that Osama Bin Laden, leader of al-Qaeda network, is still alive.

Dadullah said in the interview on Wednesday that Bin Laden planned and supervised the "suicide" operation which targeted Dick Cheney, the US vice-president, in Bargam air force base during his visit to Afghanistan on February 27.

Also on Wednesday, a district governor in the same province survived a suicide attack close to his vehicle.
