Uganda faces pressure to probe 2016 massacre by military

KAMPALA, Uganda (AP) — The United States is urging Ugandan authorities to fully investigate a military attack on a tribal king's palace two years ago that killed over 100 civilians.

The European Union is also calling for justice for victims of the November 2016 assault targeting a kingdom known as Rwenzururu, whose leader for years has been politically opposed to Uganda's longtime president.

At least 15 children were killed in the attack, according to Human Rights Watch.

The killings followed clashes between police and followers of the tribal king, who later was arrested along with hundreds of supporters. Many remain in detention.

Uganda insists the attack targeted armed militiamen and that the matter is now before the criminal justice system. No arrests of military actors have been announced, and the operation's commander was promoted.
