REUTERS - Khamis Gaddafi may be the next of Muammar Gaddafi's sons to be put on a wanted list by the Hague-based International Criminal Court (ICC).

The ICC has already approved warrants for the arrest of Gaddafi, his son Saif al-Islam, and Libyan intelligence chief Abdullah al-Senussi on charges of crimes against humanity.

Prosecutor Luis Moreno-Ocampo said he may also apply for an arrest warrant for Gaddafi's son Khamis, after Human Rights Watch said members of the Khamis Brigade, a force commanded by him, appeared to have carried out summary executions of detainees whose bodies were found in a warehouse in Tripoli.
