Uganda's First Lady has declared that if cows can't be gay then humans definitely cannot be gay either.

Janet Museveni delivered the bewildering statement during a speech to the Church of Uganda's bishops to praise their work which had "progressed" the country.

Uganda recently passed an anti-gay bill, supported by the church, which will punish homosexual acts with life sentences.

"If cows did not practice homosexuality, how could we the human beings start arguing over homosexuality?" asked Museveni, who is also Minister for Affairs in the region of Karamoja.

Museveni stated that Uganda should follow God and not repeal the anti-gay law, after more than 50 civil society groups filed opposition petitions against the bill in Uganda's Constitutional Court last week.

"We must listen to God and obey him," she said. "Thank you God for leading us."

Stricter new law

Uganda's anti-homosexual law, passed by Ugandan President Yoweri Museveni, imposes stricter laws for gays including life sentences for "aggravated homosexuality" and bringing in a law that criminalises the failure to report anyone who breaks the anti-gay law.

Homosexuality is illegal in 37 African countries and 83 worldwide, but the law passed by Museveni has led to widespread criticism in Western nations.

Norway and Denmark have decided to withhold donations to Uganda while the World Bank has postponed a $90m (£54m) loan to Uganda because of the law.

The United States has announced that it is reviewing its relationship with the African country.
