Saddam's half-brother detained

Sabawi Ibrahim al-Hassan was Saddam's advisor and intelligence chief, a key post in the old regime. No details were immediately available on the arrest but the government said it would make it a statement later Sunday.

Two other half-brothers of Saddam, Barzan and Watban, are already being held at a US army-run jail near Baghdad and are set to be tried in the coming months

Al-Hassan was one of about a dozen of the most wanted officials who have so far escaped arrest or death at the hands of American-led security forces.
