An area in Paris has been on lockdown after an armed man reportedly took several people, including a pregnant woman, hostage in one of the buildings, local media report.
"The individual has been arrested and the hostages are out of danger", Interior Minister Gerard Collomb said on Twitter.
As negotiations progressed, the hostage-taker reportedly asked to speak to the Iranian ambassador, a police union official, Yves Lefebvre, said. "The negotiator had difficulty understanding".
The man also claims to have an accomplice outside the building. At this time, police do not now believe the situation is terror-related.
The man is "armed and holding at least two people", a source told AFP, adding that "the situation is quite confused" but did not appear to be terrorism-related.
More than a dozen heavily-armed police officers, firefighters and rescue workers were stationed outside the building where the hostages were being held, located in a crowded neighborhood in the center of the French capital.
