Filthy animals.

NAIROBI, Kenya (AP) — It’s a gruesome display seen many times over the years in Mogadishu. The bodies of dead soldiers dragged through the streets. Somalis angry over 20 years of violence say they do it in hopes of driving out African Union forces.

The latest incident happened Thursday, when the body of a fighter who appeared to be a member of the AU’s peacekeeping mission was pulled through the streets by a rope. The spokesman for the country’s most dangerous militant group, al-Shabab, also displayed a body alongside documents that identified the man as a Ugandan soldier.

“Today we are celebrating the death and blood of your sons,” Sheik Ali Mohamud Rage said at a news conference Thursday.

The most infamous occurrence happened in 1993, when fighters dragged a U.S. soldier through the streets after a disastrous U.S. military assault into the Somali capital described in the book and movie “Black Hawk Down.” The deaths and grisly scene were widely used by media outlets who had to weigh the images’ news value against their violent nature. The incident hastened the U.S. withdrawal from the East African nation.

In 2007, Somalis dragged the bodies of Ethiopian soldiers through the streets. Ethiopia withdrew after two years of war.
