In 2005, in reply to a question concerning the use of non-conventional weapons in Iraq, the Italian Under-Secretary of State for Defence stated:
[T]he Italian contingent, included in the multinational division under the British command and deployed in the province of Dhi Khar … carries out its activity of humanitarian and stabilization mission as a force authorized by the UN, according to Resolution No. 1546. This contingent has always carried out its activities in compliance with the international conventions and international humanitarian law. These norms are moreover mentioned in the national operational directive, and it is therefore a specific duty and responsibility of the commander to denounce any act contrary to them.
