Ousted Iraqi president Saddam Hussein's half-brother was arrested on Sunday, official sources said.
"Sabawi Ibrahim al-Hassan has been held in Iraq," official sources said.
It is unclear whether the Iraqi or US forces arrested him. Ibrahim al-Hassan was number 36 on the US list of most wanted officials of the Saddam regime in Iraq.
Hassan was Saddam's advisor and intelligence chief, a key post in the old regime.
Two other half-brothers of Saddam, Barzan and Watban, are in the US army-run jail near Baghdad. Their trials will be held in the coming months.
