Saudi Arabia widened its rift with Iran on Monday, saying it would end air traffic and trade links with the Islamic republic and demanding that Tehran must "act like a normal country" before it would restore severed diplomatic relations. Foreign Minister Adel al-Jubeir told Reuters in an interview that Tehran was responsible for rising tensions after the kingdom executed Shi'ite Muslim cleric Nimr al-Nimr on Saturday, describing him as a terrorist. "We will also be cutting off all air traffic to and from Iran. We will be cutting off all commercial relations with Iran. And we will have a travel ban against people traveling to Iran," Jubeir said. Iranian pilgrims would still be welcome to visit Islam's holiest sites in Mecca and Medina in western Saudi Arabia, either for the annual haj or at other times of year on the umrah pilgrimage, he said.
