Q&A: UN's Agnes Callamard on drone strike that killed Soleimani

The United Nations's special rapporteur on extrajudicial, summary and arbitrary killings presented a new report to the Human Rights Council in Geneva. Agnes Callamard's investigation focused on the legality of armed drones including one that killed Iranian General Qassem Soleimani near Baghdad's airport on January 3. It concluded the United States acted unlawfully in carrying out the attack. The US, meanwhile, denounced her findings. Callamard spoke to Al Jazeera about her probe and the future of drone warfare.
