IF TRUE, TROUBLE – AT 11:35 A.M. ET:   London's Daily Mail is reporting on claims that ISIS has enough nuclear material for a dirty bomb.  A dirty bomb isn't an "atomic bomb," but a conventional explosive wrapped in radioactive material that contaminates a wide area if exploded:

Islamic State fanatics claim to have constructed a dirty bomb after stealing 40kg of uranium from an Iraqi university.

Militants boasted of the device on social media, with one even commenting on the destruction such a bomb would wreak in London, four months after the chemical was reported missing from Mosul University.

Among extremists making online threats to the West is British explosives expert Hamayun Tariq, who fled his home in Dudley, West Midlands, for the Middle East in 2012.

Using the Muslim name, Muslim-al-Britani, he posted on Twitter: 'O by the way Islamic State does have a Dirty bomb. We found some Radio active material from Mosul university,' the Mirror reports.
He continued: 'We’ll find out what dirty bombs are and what they do. We’ll also discuss what might happen if one actually went off in a public area.

'This sort of a bomb would be terribly destructive if went off In LONDON becuz (sic) it would be more of a disruptive than a destructive weapon,' before having his Twitter account suspended.
Other jihadis echoed the claims a destructive 'dirty bomb' had been made, with one writing: '
'IS has confirmed that we have acquired a dirty bomb from radioactive material from Mosul Uni! Mashallah #IS'.

COMMENT:  Can't confirm it, but it's entirely logical that extremist groups can acquire extremely dangerous materials in an unstable region.  A dirty bomb can contaminate many blocks in a big city.  It could paralyze financial districts or sports venues.  It's only a matter of time.
