Watch | Pakistani PM Nawaz Sharif heckled during speech in US

Pakistani Prime Minister Nawaz Sharif on Friday was heckled by Baloch activist Ahmar Mustikhan while delivering his speech at the US Institute of Peace, a prominent independent think-tank. Mustikhan, who disrupted Sharif's speech, chanted “anti-Pakistan” and “free Balochistan” slogans. He demanded freedom of Balochistan provinces where Pakistani army has been engaged in torture and killings of Baloch people who are demanding freedom. The activist also called Sharif a 'friend of Osama Bin Laden'. Pakistan says it is winning the battle against separatists in the restive south-western province, but Baloch activists say abductions, torture and killings by the army are deepening hostility for the government. Meanwhile, Sharif continued to address the audience and said that India is engaged in a “major arms buildup” which compels Pakistan to respond in equal measure.
