Mutassim Gaddafi killed, reports that Seif captured

Muammar Gaddafi's son Mutassim has been killed in Sirte and there are unconfirmed reports that Seif Gaddafi has been captured and may also be dead.

Pictures appeared to confirm Mutassim's death. He was in the same area where his father was captured and killed earlier today.

"We found him dead. We put his body and that of (former defence minister) Abu Bakr Yunis in an ambulance to take them to Misrata," said NTC official Mohamed Leith of Mutassim Gaddafi.

Seif Gaddafi, Muammar Gaddafi's heir apparent, was reported to have been captured after a small convoy was intercepted near Sirte.

Another of Gaddafi's sons, Khamis, was killed in August.
