The Islamic State group leader who reportedly had a $25 million bounty on his head is believed to have been killed in Syria.
A "high value ISIS target" -- believed to be Islamic State mastermind Abu Bakr al-Baghdadi -- was killed by U.S.-led forces in Idlib, a well-placed military source told Fox News on Saturday night.
A senior Trump administration official later confirmed the source's account.
At 9:23 p.m. Saturday, President Trump posted a Twitter message hinting at "very big" news.
