Ethiopia is party to the Nairobi Protocol for Prevention, Control in Reduction of Small Arms and Light Weapons in the Great Lakes Region and the Horn of Africa (Nairobi Protocol), which compels signatories to dispose of confiscated and unlicensed small arms and light weapons (SALWs). This provision is also included in Ethiopian law. According to the Ethiopian Police, between 2003 and 2004, there were 9,531 arrests and prosecutions for illegal arms transfers and possession. In addition, Ethiopia destroyed more than 11 700 small arms, 3 000 hand grenades and 170 000 rounds of assorted types of ammunition in 2006 and 2007. These arms and ammunition had either been confiscated by the police or had been voluntarily surrendered.
