Pakistan Prime Minister Yousuf Raza Gilani today rejected a US court's demand asking the ISI chief Lt Gen Ahmed Shuja Pasha to appear before it in connection with with a lawsuit filed by relatives of victims of the Mumbai attacks. Responding to members concerns in the lower house of National Assembly, Gilani said, the ISI is an extremely important sensitive institution and unless its officers agree to go to the American court, no one can send them. Earlier, Leader of Opposition in the house, Chaudhry Nisar Ali Khan described the summoning of the ISI chief by an American court as an attack on Pakistan's honour. The members of the Pakistan's parliament were agitated over Brooklyn court summoning the current ISI chief Lt Gen Pasha and his predecessor Nadeem Taj and Lashker-e-Taiba leaders, including Hafiz Saeed, to appear before it next month in connection with a suit filed by relatives of Rabbi Gavriel Noach Holtzberg and his wife. The Jewish couple was among the 166 people killed during the attacks. The lawsuit alleges that the ISI provided critical planning, material support, control and coordination for the attacks to the Pakistan-based LeT. Indian officials have blamed the LeT for carrying out the attacks and said elements of the ISI and Pakistan Army played a role in planning and facilitating the assault.
