DERA ISMAIL KHAN/MIRANSHAH, Pakistan (Reuters) - A bomb planted by Taliban insurgents ripped through a vehicle carrying Pakistani troops on Sunday, killing 20 soldiers and prompting Prime Minister Nawaz Sharif to cancel his trip to the World Economic Forum in the Swiss resort of Davos this week.
At least 30 others were wounded as the convoy prepared to leave the volatile north-western town of Bannu for nearby North Waziristan, a lawless, tribal region on the Afghan border where many al Qaeda-linked militant groups are holed up.
