CNN's Zain Verjee reports on the pope saying condoms actually contribute to the HIV/AIDS problem in Africa.

The Vatican on Wednesday defended Pope Benedict's opposition to the use of condoms to stop the spread of AIDS as scientists and countries including his native Germany criticized it as unrealistic and dangerous.

Benedict, arriving in Africa, said on Tuesday that condoms "increase the problem" of AIDS. The comment, made to reporters aboard his plane, caused a worldwide storm of criticism.
