According to government spokeswoman Faizullah Faraq, just one woman has been discovered alive thus far and is receiving medical attention at a hospital.
At least 18 people were killed when a bus carrying almost two dozen wedding guests plunged into the Indus River in northern Pakistan, according to officials.
According to government spokesperson Faizullah Faraq, the accident occurred on Tuesday in the Gilgit Baltistan region as the bus was traveling to the Punjab province city of Chakwal.
Senior Superintendent of Police Sher Khan told Pakistani news site Dawn.com that 16 dead had been found and that more are being sought.
Faraq added that only one woman had been discovered alive and was receiving medical attention at a hospital thus far.
Rescuers will start looking for missing passengers again on Wednesday, according to the police.
Unknown reason of crash
The cause of the crash was also unknown, according to police, and they had not yet recorded the statement of the lone survivor.
Asif Ali Zardari, the president of Pakistan, expressed sympathy and urged rescuers to search for the missing passengers as soon as possible.
Due to inadequate infrastructure and a lack of adherence to safety regulations and traffic laws, road accidents are frequent in Pakistan.
Two different bus crashes in August claimed 36 lives and injured scores more.
