Iran said on Sunday that the death of Daesh terrorist Abu Bakr al-Baghdadi does not mean the end of the fight against the group or its ideology.
"Baghdadi's death is not the end of fighting Deash terrorism but just the end of a chapter," government spokesman Ali Rabiei said in a tweet.
"(Deash terrorism) is still growing and evident. Growing via American policies and regional petrodollars, and evident in takfiri ideology. These three sources must be extinguished," he added.
US President Donald Trump announced Baghdadi's death on Sunday during a night time raid by US special forces deep outside the village of Barisha in Idlib province, northwestern Syria.
He said that US forces killed a "large number" of Deash terrorists during the raid which culminated in cornerning Baghdadi in a tunnel, where he set off a suicide vest.
The raid -- which required flying more than an hour by helicopter in both directions from an undisclosed base -- had been accomplished by help from Russia, Syria, Turkey and Iraq, according to Trump.
In 2014, Iran sent the commander of the elite Quds Force of its Islamic Revolutionary Guard Corps, Major General Qasem Soleimani and "military advisers" to Iraq to help it in the fight against Deash.
