US Secretary of State Mike Pompeo acknowledged on Tuesday that ISIS militants are gaining strength in some areas but said the militant group's capacity to conduct attacks has been greatly diminished.
"It's complicated. There are certainly places where ISIS is more powerful today than they were three or four years ago," Pompeo said in an interview with CBS "This Morning." But he said the group's self-proclaimed caliphate is gone and its attack capability has been made much more difficult.
Pompeo was asked about a New York Times report that the ISIS militant group was gaining new strength in Iraq and Syria.
President Donald Trump said in December that US troops succeeded in their mission to defeat ISIS in Syria and were no longer needed in the country. "We won," he said at the time.
Pompeo said the plan to defeat ISIS in the region was executed with 80 other countries and was very successful.
However, he cautioned that there is always risk that there will be a resurgence of "radical Islamic terrorist groups," including al-Qaeda and ISIS.
In Geneva, a senior Chinese official warned on Tuesday that there was a danger of ISIS militants re-emerging in Syria and called for progress in the political process between the Damascus government and the opposition to end the war.
China has long worried about ethnic Uighurs from China’s far western region of Xinjiang who have traveled clandestinely to Syria and Iraq to fight with Islamist groups there.
ISIS claimed responsibility for a wedding suicide attack that killed 63 people and wounded 182 on Saturday in the Afghan capital of Kabul.
