WASHINGTON: - The United States and the United Nations today strongly condemned the incidents of bombings in Pakistan and Afghanistan, with a call for unity among their peoples to combat the scourage of terrorism. "It is a terrible tragedy, we condemn these attacks," spokesman Sean McCormack said at the daily briefing, terming bombings in the Pakistani and Afghan capitals as terrible news. Earlier, White House national security spokesman Gordon Johndroe pledged cooperation with Pakistan in the fight against violent extremism.  "Extremists continue to show their disregard for all human life and their willingness to kill fellow Muslims. We will continue to stand with the people of Pakistan as they face this common enemy," Johndroe said. He offered condolences to the families of the victims of the tragedy near Islamabad's Melody market. Secretary-General Ban Ki-moon also strongly condemns the bombings in Islamabad and Karachi. "The Secretary-General urges all political forces to unite against the scourge of terrorism and expresses his heartfelt condolences to the families of the victims and to the Government and people of Pakistan," Ban's spokesperson Michele Montas said in a statement issued at UN Headquarters in New York. Meanwhile, the United States also condemned the deadly suicide bomb attack on the Indian embassy in the Afghan capital Kabul as "needless act of violence" in which at least 41 people, including four Indian nationals, were killed. "We condemn this needless act of violence, and offer our sincere condolences to those injured and especially to those families who lost loved ones," US national security spokesman Gordon Johndroe said. "Extremists continue to show their disregard for all human life and their willingness to kill fellow Muslims. The United States stands with the people of Afghanistan, as well as India, as we face this common enemy," Johndroe, who is accompanying President George W Bush at G-8 summit in Japan, said. The top U.N. official in Afghanistan, Kai Eide, said, "In no culture, no country, and no religion is there any excuse or justification for such acts. The total disregard for innocent lives is staggering and those behind this must be held responsible." Also condemning the attack, Ban Ki-moon reiterated that "no political agenda or grievance can justify such reprehensible means." In a statement issued by his spokesperson, Ban urged that those responsible be brought to justice.
