US Secretary of Defense Jim Mattis was among the 27 defense ministers, as well as senior representatives from seven coalition nations whose ministers were unable to attend Thursday's meeting.
NATO Secretary General Jens Stoltenberg welcomed the delegates in Brussels to discuss efforts to defeat Daesh in Iraq and Syria and to get an update on the current military plan through 2017.
Following the rise of Daesh in 2014, the US-led coalition of 68 nations was formed to counter the group. The alliance is conducting airstrikes against Daesh in Syria and Iraq. The strikes Iraq are conducted in support of the Iraqi government, but those in Syria are not authorized by the government of President Bashar Assad or the UN Security Council.
Russia launched its military operation in Syria on September 30, 2015, at the request of the Syrian government. While targeting terrorist organizations, Russia also acts as a mediator in the intra-Syrian reconciliation process, and provides Syrian civilians with humanitarian aid.
