A spokesperson for the UN Secretary-General said:
The Secretary-General is deeply concerned about ongoing terrorist violence in Pakistan.
He strongly condemns the multiple attacks today in Quetta (Balochistan) and the Swat Valley that have reportedly killed at least 100 people and injured at least 200 more.
He also strongly condemns yesterday’s targeted killing of Dr. Syed Riaz Hussain who was the President of the Pakistan People's Party for Kurram Agency in the Federally Administered Tribal Areas. Dr. Hussain was a strong advocate of democracy and tolerance.
These heinous acts cannot be justified by any cause.
The Secretary-General conveys his heartfelt condolences and deepest sympathies to the Government and people of Pakistan, as well as to the families of all the victims.
He reiterates the strong support of the United Nations for the efforts of the Government of Pakistan to combat the scourge of terrorism and hopes that the perpetrators of these violent acts will be brought to justice.
