Iraqi officials say the death toll from the sinking of a ferry overloaded with people celebrating the Kurdish new year in northern Iraq has risen to 71.
Maj. Gen. Saad Maan, a spokesman for the Interior Ministry, says 71 people died and another 55 have been rescued, including 19 children.
Officials say the ferry sank in the Tigris River near the northern city of Mosul because of a technical problem, and that there weren't many boats in the area to rescue people.
An Iraqi official says a ferry overloaded with people celebrating the Kurdish new year sank in the Tigris river near Mosul, killing at least 40 people.
Col. Hussam Khalil, head of the Civil Defense in the Nineveh province, told The Associated Press that the accident occurred on Thursday as scores of people were out in the tourist area celebrating Nowruz, which marks the Kurdish new year and the arrival of spring.
Khalil says many of the dead were women and children, adding that search operations are still underway.
