Osama bin Laden’s fifth wife has claimed that the killed al-Qaeda leader was not on kidney dialysis, but used to take Viagra during his stay in his Pakistani compound.

Insisting that bin Laden used to take the herbal impotence drug, Amal al-Sadeh, who was shot in the leg when SEALs burst into their bedroom and killed the terror leader, said: "He believed in his own medication."

Osama Bin Laden wasn't on kidney dialysis - but he did need a herbal impotence drug.

The New York Daily News quoted the Yemeni woman as saying that her husband had fully recovered from two kidney surgeries a decade ago, and that he needed no dialysis before his death, but cured himself with his own regimen, which included watermelons.

It was also reported that the Saudis had hired an assassin to poison Bin Laden in 1999, and the toxin gave him kidney failure.
