Five people have been killed in a mid-air collision between a small tourist plane and a helicopter carrying skiers to a glacier in the Italian Alps, officials said.
Two other people were injured, at least one seriously.
Rescue workers said those on board were off Swiss and French nationality.
The rescue operation was suspended on Friday evening and will resume again on Saturday, Alpine rescue corps said.
The accident happened on Friday afternoon at an altitude of about 3,000 meters (9,800ft) over the Rutor glacier in the north-western region of Val d’Aosta, spokesman Walter Milan said.
The cause of the crash remained unclear as rescue crews worked to remove the bodies. The identities and nationalities of the victims have not been released.
The Rutor glacier covers nine square kilometres (3.5 square miles) and is the second-largest in the Val d’Aosta region, which borders France.
The region’s website says skiers frequently access it by helicopter during winter.
