TEHRAN (AFP/Reuters) - Iranian President Mahmoud Ahmadinejad hit out at neighbouring Pakistan over a deadly bombing against Irans Revolutionary Guards, accusing it of sheltering Jundallah militants. He charged that the attack had been plotted from Pakistan, calling on it not to waste time in cooperating with Iran in apprehending the perpetrators, the semi-official Fars News Agency reported. We were informed that some security agents in Pakistan are cooperating with the main elements of this terrorist incident ... We regard it as our right to demand these criminals from them, Ahmadinejad said, without giving details. We ask the Pakistani government not to delay any longer in the apprehension of the main elements in this terrorist attack, he said. Iran summoned Pakistans envoy to Tehran over the attack, claiming those behind the attack had used Pakistani soil as a springboard, the ISNA news agency said. It said the Foreign Ministry had called Pakistans charge daffaires and expressed Tehrans regret to Pakistans envoy (that) members of the terrorist group involved in the incident entered Iran through Pakistan. The Ministry also protested against the use of Pakistani territory by the terrorists and rebels against the Islamic Republic of Iran and urged Pakistani authorities to act firmly to prevent the movement of those terrorists and rebels in their country. Irans Foreign Ministry says there is evidence the perpetrators of this attack came to Iran from Pakistan, Press TV reported. The Pakistani official assured Tehran that his country would take all measures to secure its border with Iran. Iran has in the past accused Pakistan of hosting members of the Jundallah group, Press TV said. APP adds: Foreign Office Spokesman Abdul Basit has condemned the suicide attack in Iran. The spokesman said that both the countries enjoy brotherly ties and We condemn the sad event in Iran. Refuting Jundollahs presence in Pakistan, Basit said that both the countries have mutual interim and bilateral mechanism and cooperated with each other on critical issues. He said that some elements wanted to disrupt good ties between the two brother countries, which are linked in religious, cultural, and trade bonds. Basit assured Iran full cooperation in this critical situation. Abdul Basit, reacting to the statement of Iranian ambassador Mashallah Shakeri Sunday, denied having any information about presence of extremist organisation Jundallahs chief in Pakistan. Talking to a private TV channel, the FO spokesman rejected the Iranian ambassadors statement about the presence of head of the Jundallah group. The spokesman said Pakistan and Iran are cooperating in the war against terrorism as both countries enjoy friendly relations. Basit said the war against terrorists in Pakistans tribal area of South Waziristan reflects Pakistans commitment that it will not allow its soil for terrorist activities in any country. Pakistan is not involved in terrorist activities, he said, adding: We are struggling to eradicate the menace of terrorism. He said that such statement could sour relations between the two countries.
