The daughter of Afghanistan’s ambassador to Pakistan was abducted in the middle of the Pakistani capital of Islamabad, held for several hours and brutally attacked, officials in both countries said on Saturday. No one has been arrested in connection with Friday’s assault on Silsila Alikhil, 26. The Afghan foreign ministry issued a statement demanding a quick investigation, saying she was “severely tortured”. A hospital medical report, seen by the Associated Press, said she suffered blows to her head, had rope marks on her wrists and legs, and was badly beaten. There was a suspicion that she had several broken bones and X-rays were ordered, the report said. The report said her abductors held her for over five hours and that she was brought to the hospital in Islamabad by police. There were no details about the abduction itself or the circumstances of her release. Pakistan called the attack “disturbing” and said security at the residence of the Afghan ambassador in Islamabad has been reinforced. The Afghan foreign ministry said it strongly condemned this “heinous act” and expressed concern for Afghan diplomats and their families in Pakistan. Relations between the two countries are fraught with suspicion and animosity. They routinely trade accusations, with Afghanistan claiming that Pakistan is sending thousands of jihadi militants across the border to fight and providing a safe haven for the Taliban. Pakistan in turn accuses Kabul of harbouring the anti-Pakistani group Tehreek-e-Taliban Pakistan – the Pakistani Taliban – and the secessionist Baluchistan Liberation Army. As violence escalates in Afghanistan in concert with the withdrawal of US and Nato troops, some within the Afghan government have stepped up their verbal assaults on Pakistan. In Kabul, the Afghan foreign ministry summoned the Pakistani ambassador, Mansoor Ahmad Khan, on Saturday to lodge “a strong protest” over the attack. The ministry said it “explicitly called on the Pakistani government to take immediate action to identify and punish the perpetrators of this crime”. A leading female senator in Pakistan, Sherry Rahman, condemned Friday’s attack and tweeted that “the Afghanistan ambassador’s daughter is a young woman, and should not face any obstacle in walking about in central Islamabad … More importantly, she is entitled to diplomatic protection in Pakistan.” Hamid Mir, a Pakistani journalist who survived a 2014 shooting in the southern city of Karachi, asked in a tweet how something like this could happen in Islamabad. “What is the use of expensive safe city cameras?” He also noted that Pakistani journalists and even a police officer have been abducted in Islamabad, yet few culprits have been arrested. Most of Islamabad’s neighbourhoods are upmarket, with wide, tree-lined boulevards. The Pakistani capital is home to all the diplomatic missions in the country, the majority of them located inside a heavily fortified enclave. The Afghan mission, however, is outside that enclave. Pakistan’s foreign ministry said in a statement that “the safety and security of the diplomatic missions, as well as the diplomats and their families, is of utmost importance. Such incidents can and will not be tolerated.”
