(Persia Digest) - Iran filed a diplomatic protest against the United States on Monday after its national men's volleyball team experienced a "prolonged delay" at a Chicago airport, the Islamic Republic News Agency (IRNA) reported.
CNN reports that top Iranian foreign ministry official for US affairs, Mohsen Baharvand, filed the complaint through the Swiss ambassador to Tehran -- which represents US interests in Iran, as the country has no diplomatic relations with Washington.
Baharvand said if the US cannot host sports teams fairly and unbiased, it would be better to avoid hosting sports events, IRNA reported.
US Customs and Border Protection spokesman Steve Bansbach told CNN in a statement that "normal CBP procedures were followed and everyone was processed without incident" at O'Hare Airport.
The complaint comes at a time of heightened tensions between Iran and the US. Tehran has begun increasing uranium enrichment, after US President Donald Trump withdrew from a landmark 2015 nuclear deal and re-introduced economic sanctions in 2018.
