The United States has suspended some aid to Uganda over passage of a controversial anti-gay law.

The measure, signed last month by Ugandan President Yoweri Museveni, calls for life imprisonment for the crime of “aggravated homosexuality,” outlaws the promotion of gay rights and requires individuals to turn in anyone they suspect of being gay.

According to Reuters, the U.S. Center for Disease Control (CDC) has put on hold an assistance program to Uganda's ministry of health.

“As a result of this review process, a portion of the U.S. Center for Disease Control's (CDC) cooperative agreement with the Ministry of Health has been put on hold pending this review,” a senior U.S. government official is quoted as saying.

How much aid was withheld was not disclosed.

Rukia Nakamatte, a spokesman for Uganda's health ministry, said the cuts would affect 50 of its workers. The ministry uses a fund controlled by the CDC to buy antiretroviral drugs and HIV testing kits.

Five donors – the World Bank, Sweden, Norway, Denmark and the Netherlands – have also suspended part of their financial aid or loans to the nation.
