KABUL: Hundreds of Afghans took to the streets of Kabul on Sunday to condemn recent shelling of border towns by Pakistanâ€™s army and accusing its powerful spy agency of involvement in the assassination of the countryâ€™s ex-President Burhanuddin Rabbani. The protest comes amid heightened tensions between two neighbours, with Afghan officials blaming Pakistanâ€™s Inter-Services Intelligence (ISI) and the Talibanâ€™s senior leadership of plotting to kill Rabbani. Under tight security, the one-hour rally passed without any incidents. But protesters appeared angry and carried large banners with slogans as they chanted â€œDeath to Pakistanâ€ and â€œDeath to ISIâ€. â€œPakistan and its ISI must stop interfering in Afghanistan. Our patience is running out,â€ said Daoud Kodamani, a 22-year-old university student. â€œFighting our countryâ€™s enemies is nothing new for Afghans and Pakistan is another enemy to fight with,â€ he said. Many Afghans have long accused Pakistan and the ISI of backing insurgent groups to further Islamabadâ€™s own interests, which Pakistan denies. Rabbani, who was head of the High Peace Council tasked with trying to reach a negotiated settlement to the 10-year war, was killed at his Kabul home on Sept. 20 by a suicide bomber claiming to be carrying a message of peace from the Taliban leadership. Rabbaniâ€™s killing was widely seen a major blow to the peace process and came amid worsening security in the country as NATO-led troops begin handing security responsibility to Afghan troops in preparation for full withdrawal from the country by the end of 2014. Afghan President Hamid Karzai hinted on Saturday he had lost hope in pursuing peace talks with the Taliban, whose leadership council, or Shura, is believed to be based in the Pakistani city of Quetta. Karzai said Afghanistan should be negotiating peace with Pakistan instead. Afghan provincial officials say Pakistanâ€™s military had fired hundreds of rockets between Sept. 21 and Sept. 25 in eastern Kunar and Nuristan provinces, which share a long border with lawless tribal areas inside Pakistan. Although, the shelling did not cause major casualties, it followed more than a month of bombardments by Pakistanâ€™s military in June and July that Afghanistan said had killed at least 42 people. Pakistan has repeatedly blamed Afghanistan for giving safe haven to militants on its side of the border, particularly in Kunar province, leaving it vulnerable to counter-attack when it chases them out of its own ethnic Pashtun tribal areas.
