A Foreign and Commonwealth Office spokesperson said:
The UK and a number of European partners today jointly raised with Iran our deep concerns about hostile activities and plots being planned and perpetrated in Europe. Such actions are unacceptable and must have consequences.
We informed the Iranian authorities that those responsible for the June 2018 bomb plot planned in France are being included on the EU list of persons, groups and entities involved in terrorist acts and will be subject to restrictive measures.
We also condemned other illegal activities, including the recent thwarted assassination plot in Denmark and two assassinations in the Netherlands.
We remain committed to the Joint Comprehensive Plan of Action, for as long as Iran continues to implement it in full. This agreement remains central to international efforts to halt nuclear proliferation and is crucial for the security of the region. But we are clear that this commitment does not preclude us from addressing other hostile and destabilising activities.
