NEW DELHI: India rebuked Pakistan again Thursday for not punishing the masterminds of the 2008 assault on the Indian financial capital that killed 166 people. None of the seven men arrested in Pakistan on charges of planning and executing the three-day assault - which began two years ago Friday - have been put on trial. An External Affairs Ministry official said a formal complaint was sent to Pakistan but would not reveal its contents. The Press Trust of India reported that the message expressed New Delhi's frustration that Islamabad had not followed up on intelligence passed to Pakistan about the men, who belong to Lashkar-e-Taiba, a Pakistan-based Islamist militant group. Relations between the two South Asian rivals have been strained since the attacks, US solidarity with India Two years after the 2008 Mumbai attacks killed 166 people, the United State stands “in solidarity” with India, Secretary of State Hillary Clinton said. “As the people of the United States gather with family to celebrate Thanksgiving, we pause to remember the horrific attack on innocent men, women and children that occurred in Mumbai two years ago,” Clinton said in a statement late Wednesday. “Now, as then, the American people stand in solidarity with the people of India and honor those who lost their lives.” During a visit to India earlier this month, US President Barack Obama shared with Indian Prime Minister Manmohan Singh the results of a probe that found US intelligence did not pass on warnings about David Headley, an American who played a key role in the attacks. The president stayed in the Taj Mahal Palace hotel in Mumbai, which became the focus of the assault by 10 militants, and met survivors and victims' relatives, hailing their courage and pledging to stand with India to fight terrorism. “President Obama's recent visit to India underscored our nations' shared belief in liberty, democracy and mutual respect for all people,” Clinton said. “As the people of Mumbai gather in temples, mosques, churches, gurdwaras and synagogues to honor those who perished on November 26, 2008, they send a message of resolve, resilience and mutual respect that is far louder and more powerful than any terrorist's guns and bombs.”
