( dpa ) - Iranian Foreign Minister Manouchehr Mottaki said on Friday that the assassination of the former Pakistani prime minister Benazir Bhutto was an attack on Pakistan's security. "Those who have done this crime have targeted the security, stability and the national unity of Pakistan," he told the reporters at Bhutto's Pakistan People's Party (PPP) central office in Islamabad. The stability of Pakistan, and the security of Pakistan will affect the whole region and vise versa, added Mottaki, a few hours after his arrival in Pakistan on a one-day visit. The minister was due to visit Bhutto's home town, Noudero, in the southern province of Sindh to express condolences to her family but cancelled the trip over security concerns on the advice of the Pakistani government. Mottaki vowed to eliminate extremism and terrorism from the region and said those involved in Bhutto's murder should be arrested and punished according to the law. Benazir Bhutto was murdered on December 27 when an attacker shot at her with a pistol as she was greeting her supporters from the sunroof of her bullet-proof vehicle following a public rally in the garrison city of Rawalpindi. The attack was followed by a suicide bombing which killed more than 20 people. Separately, the Iranian minister also met President Pervez Musharraf, Prime Minister Mohammedmian Soomro and Foreign Minister Inamul Haq and discussed several bilateral issues.
