India's top diplomat inspected the site of a huge bomb attack on the Indian embassy in Kabul Friday but declined to point a finger of blame for a strike that could escalate regional tensions. The attack Thursday, which killed 17 people but harmed no embassy staff, has renewed focus on India's tense relations with Pakistan. India has in the past accused Pakistan's ISI spy agency of being behind attacks on Indian interests in Afghanistan. An attack on the same Kabul embassy last year killed 58 people. Indian Foreign Secretary Nirupama Rao declined to make any accusations as she toured the heavily fortified embassy compound, its premises littered with shattered glass and debris from the blast that wounded up to 80 people. “I think the investigation should be completed,” she said when asked if India thought Pakistan was behind the attack. “Whoever is responsible for this attack is against peace, is against democracy, is against people of Afghanistan and against the people of India,” said Rao, India's most senior professional diplomat, who reports to Foreign Minister S.M. Krishna. Embassy officials said she was due to meet Afghan President Hamid Karzai and Foreign Minister Rangeen Dadfar Spanta later in the day to discuss security.
