It is for individual States to determine in what way they might best contribute to the concerted international effort underway to tackle the threat posed by Daesh and other UN-designated terrorist groups. Security Council resolution 2249 grants authority for States to take all necessary measure to suppress and eradicate terrorist acts by Daesh and Al-Nusra Front in territory under Daesh control within Syria and Iraq and to eradicate the safe haven they have established inside Syria and Iraq. Any action undertaken under this resolution must be in compliance with international law, in particular the UN Charter, as well as international human rights, refugee, and humanitarian law.
