A Ugandan lawmaker first introduced the bill in 2009, sparking worldwide condemnation for tough measures that included the death penalty.
It was briefly shelved amid the backlash. At the time, some European nations threatened to withdraw aid to Uganda, which relies on millions of dollars from the international community.
Before its passage Friday, parliament adjusted the death penalty clause to life in prison for "aggravated homosexuality." It includes acts where one person is infected with HIV, "serial offenders" and sex with minors, Amnesty International said.
In cases where one has HIV, the punishment applies even when the sex is consensual or protected.
"Ugandans have been anxiously waiting for this bill. This day will be a good day for all Ugandans," said Benson Obua Ogwal, a member of parliament for Moroto.
