France has banned far-right Turkish group Grey Wolves.
The organisation has been accused of “extremely violent actions” and spreading “extreme violent threats”.
It was also accused of creating “incitement of hatred against authorities and Armenians”.
Grey Wolves is linked to a top ally of Turkish President Recep Tayyip Erdogan.
It is seen as a militant wing of Nationalist Movement Party.
The party is allied with Erdogan’s Justice and Development Party in Turkish parliament.
France’s move follows the defacement of an Armenian memorial near Lyon last weekend.
It had “Grey Wolves” and “RTE”, initials of the Turkish President, written on it.
The ban follows escalating tensions between Paris and Ankara over France’s fight against extremism.
Turkey also backs Muslim majority ally Azerbaijan in its conflict against Christian majority Armenia over the Nagorno-Karabakh conflict.
Ankara has vowed to “respond in the firmest way possible” to the ban.
