The parents of American college student Otto Warmbier have filed a claim for a seized North Korean cargo ship in a bid to collect a multimillion-dollar judgment in the young man's death.
Attorneys for the Warmbiers said in a court filing they had a right to the assets after North Korea failed to respond to their wrongful death claim.
The Warmbiers say their son was tortured after being convicted of trying to steal a propaganda poster and imprisoned for months.
He died days after being returned to the US in a vegetative state in 2017.
A US judge has ordered North Korea to pay more than $500 million in the Warmbiers' wrongful death suit.
