Prime Minister Nawaz Sharif on Sunday called off his visit to Switzerland in the wake of a deadly bomb attack on military convoy in Bannu.
The PM was scheduled to attend the annual summit of World Economic Forum (WEF) in Davos.
In a statement, Prime Minister Sharif said that the whole nation was united on the issue of terrorism, adding that sacrifices of security forces would not go in vain.
Hours before the announcement, Imran Khan criticised Prime Minister Sharif for his foreign visits amid escalating violence in the country.
