The Pakistani Taliban denied involvement in an attack in the northwest of the country on a police convoy escorting ambassadors and diplomatic officials from a number of countries, including Bosnia and Herzegovina, and authorities say they are still trying to determine who was behind it, the Associated Press reported on Monday.

Most of the ambassadors and senior envoys were travelling with family members on Sunday to the Swat Valley, a former stronghold of the Pakistani Taliban, when the blast occurred at Malam Jabba, one of two Pakistani ski resorts in the Khyber Pakhtunkhwa province that borders Afghanistan.

Ambassadors and officials from Bosnia and Herzegovina, Indonesia, Portugal, Kazakhstan, Zimbabwe, Rwanda, Turkmenistan, Vietnam, Iran, Russia and Tajikistan travelled in the convoy.

In the report of the Pakistani media, it was stated that the diplomats were deeply shaken by this event. The media published a video of the scene of the accident, but also of the moment when the injured were transported to the hospital. A large number of residents helped the people from the convoy.

Bosnia's Foreign Ministry announced that there were no injuries in the explosion that occurred near the convoy that was securing diplomats from Bosnia and Herzegovina in Pakistan.
