(CNN) All are feared dead after a Tara Air plane carrying 23 people -- two of them babies -- crashed Wednesday morning in mountainous northern Nepal midway through what should have been a 19-minute flight, officials said.

Most of the 19 bodies retrieved as of early Wednesday evening were charred beyond recognition, said Bishwa Raj Khadka, deputy police superintendent for Myagdi district.

Search efforts at the crash site some 16,000 feet (4,900 meters) above sea level have been hampered by dense fog, according to Khadka.

Tara Air spokesman Bhim Rai initially said 21 people were on board, with three crew members among them. He updated the number to 23 -- including two foreigners, one Chinese and one Kuwaiti -- after learning that two infants were also on the plane, even if their names were not on the initial report.

The aircraft was supposed to have flown from Pokhara -- one of the most popular tourist destinations in Nepal -- to Jomsom, the gateway for one of the most popular Himalayan trekking routes.
