A More Secure World: Our Shared Responsibility, A/59/565On 19 August 2003, a truck bomb exploded at the UN headquarters in Baghdad, killing the top United Nations envoy in Iraq, Sergio Vieira de Mello, and 21 others. Secretary-General Kofi Annan denounced the bombing as an inexcusable "act of unprovoked and murderous violence." A month later, on 22 September, another suicide bomber struck a police checkpoint outside the UN headquarters killing an Iraqi policeman and wounding nineteen people, including two UN workers. After the second attack Secretary-General Annan announced the creation of a High-Level Panel on Threats, Challenges, and Change. On 2 December 2004, "A More Secure World: Our Shared Responsibility", was published by the Panel. It made recommendations for change in six areas identified as the greatest threats to security in the 21st century: poverty & environmental degradation, terrorism, civil war, conflict between states, the proliferation of weapons of mass destruction, and organized crime.
