Muammar Gaddafi's son Seif al-Islam without a doubt would get a death sentence if tried in Libya, his lawyer told the Hague-based International Criminal Court today.

"Although the Libyan government has danced around the issue, let's be very clear: if convicted (in Libya) Mr Gaddafi will be hanged," Melinda Taylor, a court-appointed lawyer, told judges amid a dispute on where Seif should face justice.

While the ICC wants Seif, the only son of the slain Libyan leader in custody, to be tried in The Hague, Libya's post-revolutionary authorities insist he should stand trial in his home country. Libya's lawyers told a three-judge bench yesterday the country had enough evidence to charge Seif with crimes against humanity, committed when Gaddafi and his loyalists tried to put down Libya's bloody revolution last year.
