While the search for the missing was called off overnight, a decision on whether to continue was expected Thursday morning. The carrier Baltic Ace began sinking immediately after it collided with the container vessel Thursday evening in a busy shipping lane, about 60 kilometers (32 miles) west of Rotterdam, according to Coast Guard spokesman Peter Verburg. Thirteen crew members were rescued and taken to hospitals in Rotterdam and at the Koksijde Air Base near Ostend, Belgium. Those rescued were suffering from hypothermia and minor injuries, the spokesman said.
