Iranian customs office (IRICA) said on Monday that movement through four crossings into Iraq had been suspended and a fifth major gateway to the neighboring country will stop processing passengers as of Tuesday, Press TV reported.
IRICA spokesman Rouhollah Latifi said the decision was meant to contain the spread of the coronavirus variant first detected in Britain amid fears that the infection is spreading fast in provinces on the Iraqi border.
Latifi said the ban would be inclusive and would apply to passengers with special travel permits, including diplomatic staff.
Reports suggested the closures would be in place at least for two weeks while borders will remain open to cargo trucks.
