Prime Minister Sharif had stated in London on Thursday that peace talks with the Taliban had been started and he would speed up the process on his return to the country.
Officials said the prime minister returned home late Saturday and would discuss the situation post-US attack with his close aides and ministers.
Opposition parties are mounting pressure on the government to cut the supply line for the US-led NATO troops in neighbouring Afghanistan in protest against the latest strike that has caused serious setback to the process of peace talks with Taliban.
