KAMPALA (Reuters) - Ugandan President Yoweri Museveni will meet lawmakers from his party on Thursday to discuss a strict anti-LGBTQ bill ahead of a deadline to sign it, veto it or send it back to parliament for revisions.

Human rights activists and the U.S. government say the bill is among the harshest pieces of legislation to target sexual minorities anywhere in the world.

It would impose the death penalty for so-called aggravated homosexuality, which includes having gay sex when HIV-positive, and 20-year sentences for "promoting" homosexuality.

Its passage last month with near unanimous support in parliament has already triggered a wave of arrests, evictions and mob attacks against LGBTQ Ugandans, members of the community say.

By law, Museveni has 30 days from when parliament sent him the bill to weigh in. The bill was passed on March 21 but it is not clear when it was transmitted to Museveni.

The president, a strong opponent of LGBTQ rights who last month called gay people "deviations from normal", has not indicated what he plans to do.

He signed a law in 2014 that stiffened penalties for same-sex relations but has also suggested at times that homosexuality should be addressed through treatment rather than legislation.

The meeting with lawmakers from his National Resistance Movement party is scheduled to begin at 2 p.m. (1100 GMT) at the presidential palace.

Same-sex relations are already illegal in Uganda, as they are in more than 30 African countries, but proponents of the bill said stronger legislation was needed to combat the threat homosexuality presents to traditional family values.

Lawmakers in neighbouring Kenya and Tanzania have recently called for similar measures in their countries.
