A Foreign Office spokesperson said:
Reports that Iran has carried out a satellite launch – using ballistic missile technology – are of significant concern and inconsistent with UN Security Council Resolution 2231. The UN has called upon Iran not to undertake any activity related to ballistic missiles designed to be capable of delivering nuclear weapons. Iran must abide by this.
We have significant and longstanding concerns, alongside our international partners, over Iran’s ballistic missile programme, which is destabilising for the region and poses a threat to regional security.
