These attacks will occur in “unexpected locations” around the world, says the report, which was authored by a committee of the UN’s Security Council that monitors the impact of UN-imposed international sanctions designed to weaken the Islamic State, al-Qaeda and groups aligned with them.

On April 21 of this year, the Islamic State (known also as the Islamic State of Iraq and Syria, or ISIS) claimed responsibility for nine suicide blasts that targeted Catholic churches and five-star hotels in Sri Lanka’s western and eastern coastal regions. The near-simultaneous bombings killed 258 people and injured over 500. They are believed to constitute the bloodiest terrorist attack in Sri Lanka’s history. But the United Nations report published on Wednesday claimed that the Sri Lanka attacks were the beginning of a worldwide campaign by ISIS, which will continue to occur throughout 2019. The absence of major ISIS attacks after April 21 is a temporary “abatement”, says the report, and will likely end before the this year concludes. Between now and then, “more Islamic State-inspired attacks will occur”, it notes. Since the fall of its self-styled caliphate in the Middle East, the militant Sunni group has maintained a sophisticated online media profile and propaganda campaign and continues to “aspire to have global relevance”, according to the report. To achieve this aim, the Islamic State’s leadership believes that the group must continue to carry out large-scale international attacks. In their effort, ISIS planners are assisted by the group’s substantial fortune, which is estimated to approach $450 million. These funds are being used to sponsor terrorist operations by ISIS affiliates in Asia, Africa and the Middle East, the report claims.

In an earlier intelligence report published in August of last year, the United Nations warned that the Islamic State had recovered from its recent defeats in the battlefield and retained as many as 30,000 committed members in Iraq and Syria alone. The report appeared to contradict earlier proclamations by the Iraqi government that the war against the group had been won. Similar proclamations were issued last year by United States President Donald Trump, who said that the war against the militant Sunni group was “98 percent” over.
