"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," a Foreign Office spokesman said.
"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," the spokesman said.
"We have significant and longstanding concerns, alongside our international partners, over Iran’s ballistic missile program, which is destabilizing for the region and poses a threat to regional security," the Foreign Office spokesman said.
