United Nations (UN) Secretary General Ban Ki-moon has called on the members of the world body to implement the sanctions imposed on Takfiri ISIL terrorists. “Member states must meet their obligation to implement and enforce the targeted financial sanctions, arms embargo and travel ban imposed on ISIS (ISIL),” the UN chief wrote in a report to the UN Security Council on the world body’s political mission in Iraq on Tuesday. Al-Qaeda-linked groups, including ISIL, have been listed as terrorist entities under sanctions by the UN. Ban further denounced the crimes being committed by the terrorist group, describing their acts of terrorism and violence as “extremely disturbing.” “I strongly condemn the upsurge of violence at the hands of ISIS and its supporters and call on (U.N.) member states, including Iraq’s neighbors, to come together and support Iraq in its fight against terrorism,” Ban wrote. “Terrorism must not be allowed to succeed in steering Iraq away from its path towards stability and democracy,” he added. The crisis in Iraq escalated after Takfiri ISIL terrorists took control of Mosul on June 10, which was followed by the fall of Tikrit, located 140 kilometers (87 miles) northwest of the capital. The militants have also declared a “caliphate” in the overrun areas. Iraqi Prime Minister Nouri al-Maliki has said Saudi Arabia and Qatar are responsible for the security crisis and growing terrorism in his country, denouncing Riyadh as a major supporter of global terrorism.
