Speaking in Mumbai yesterday, on the first day of his three day visit to India, Obama asserted that the two countries are working together more closely than ever before and were sharing intelligence to prevent terror attacks. He said he is looking forward to further deepen this cooperation to counter terrorism when he meets Prime Minister Dr. Manmohan Singh in New Delhi. Paying homage to the victims of 26/11 terror attacks, Obama hailed their resolve and resilience which stood in stark contrast to the savagery of the terrorists, he said he had purposely chosen Taj Hotel for his stay as well as his first official engagement to send an absolute message against terror. He said, the perpetrators of the Mumbai attack must be brought to justice.
