A man in Uganda faces the death penalty after being charged with "aggravated homosexuality".

His lawyer told Reuters the 20-year-old was the first to be prosecuted for the offence under tough new anti-LGBTQ legislation signed into law in May.

According to the charge sheet, he is accused of unlawful sexual intercourse with a 41-year-old man, although no further details were given.

"Aggravated homosexuality" can involve sex with children or vulnerable people.

It can also be deemed aggravatedif someone is forced to have same-sex relations, contracts a life-long infection including HIV or in cases of serial offenders.

The East African nation has among the harshest anti-LGBTQ laws in the world, and anyone convicted of engaging in homosexual acts faces life imprisonment.

The legislation has drawn widespread criticism outside the country and promptedthe World Bank to halt loans to Uganda earlier this month.

Several people have been arrested this month for allegedly engaging in same-sex activity.

The man charged with aggravated homosexuality appeared in court on 18 August in the eastern city of Soroti, Jacquelyn Okui, spokesperson for the state prosecutors, told the AFP news agency.

She told Reuters he will remain in custody until his case is heard by the High Court, given it was a capital offence.

His lawyer, Justine Balya, told Reuters she felt Uganda's anti-gay laws were unconstitutional and were currently being challenged in court.

She gave no further details of the case, except to say it was the first aggravated homosexuality charge before the courts.

Uganda has not carriedout an execution since 2005, but capital punishment has not been abolished. (BBC)
