Alireza Yousefi, director general for Western Europe at Iran’s Foreign Ministry, delivered a “strong protest” to the UK diplomat. The UK Foreign Office denied that Ambassador Hugo Shorter was formally summoned, with ITV citing sources saying he only “had a meeting” at the Foreign Ministry. London police said officers made arrests for aggravated trespass and assault on an emergency worker following the incident.The protests in Iran began on December 28 after the national currency collapsed, triggering sharp increases in food and staple prices. Demonstrations quickly escalated into riots and clashes with security forces, reportedly resulting in hundreds of deaths.
