From The AP:
Rescuers were continuing to search a fast flowing river in Nepal on Saturday after a landslide swept two passenger buses carrying more than 50 people into the swollen river early on Friday.
Continuous rain and more landslides were making rescue efforts difficult.
Three survivors apparently swam to safety, but rescuers found no trace of the buses, which likely were submerged and swept downstream in the Trishuli River.
Nepal's rivers generally are fast-flowing due to the mountainous terrain. Heavy monsoon downpours in the past few days have swollen the waterways and turned their waters murky brown, making it even more difficult to see the wreckage.
Home Minister Rabi Lamichhane told parliament 51 passengers were missing and more than 500 rescue personnel have been assigned to the search operation.
Police and army personnel were searching using rubber boats. Divers with scuba gear were also dispatched, according the Chitwan district police.
The buses were on the key highway connecting the capital to southern parts of Nepal when they were swept away around 0300 near Simaltal, about 120 kilometers (75 miles) west of Kathmandu.
Monsoon season brings heavy rains to Nepal from June to September, often triggering landslides in the mountainous Himalayan country.
Meanwhile, the government has also imposed a ban on passenger buses travelling at night in the areas where weather warnings have been issued, according to the Home Ministry.
