The acquisition of T-72s has caused significant controversy. Thirty-three vehicles ordered from Ukraine were hijacked by Somali pirates. The Ukrainian Defence Minister Yury Yekhanurov confirmed 33 Russian T-72 tanks and "a substantial quantity of ammunition" were aboard the captured cargo ship, called the "Faina"". The ship they were being carried in, MV "Faina" was released and the tanks unloaded in the port city of Mombasa in February 2009. There have been doubts expressed as to whether the T-72s imported by Kenya are intended for use by the Kenyan Army. Instead, popular opinion is that they were being clandestinely imported for the South Sudanese army, which has an arms embargo against it.
