THE FATBOY SHOW : Suicide bomber killed in Uganda on Christian holy day, army says.

Two people who the Ugandan army describe as "armed terrorists" have been killed in the capital, Kampala, as the country marks Martyrs Day - a Christian celebration to commemorate the faithful who died in the 19th Century.

A counter-terrorism unit "intercepted and neutralized" the two, one of whom was a female suicide bomber, in the upmarket suburb of Munyonyo, army spokesperson Chris Magezi said.

The incident took place near the Roman Catholic Munyonyo Martyrs' Shrine, where a group had gathered to pray, local media reported.

Reports also cited an explosion, with an eyewitness telling Uganda's Daily Monitor newspaper that the blast occurred as the two approached the church on a motorcycle.
