The U.K. joined the U.S. in banning laptops and other electronic devices in airplane cabins on flights from several Middle Eastern countries amid concerns over security. Inbound direct flights from Turkey, Lebanon, Jordan, Egypt, Tunisia and Saudi Arabia will be affected by the ban on laptops and tablets, Prime Minister Theresa May’s spokesman James Slack told reporters in London on Tuesday. Phones larger than normal-sized mobiles or smartphones will also be forbidden. “We have been in close contact with the Americans throughout this process,” Slack said as he announced the details, which earmark a different list of countries from those on which restrictions were imposed by the U.S. earlier on Tuesday. “We’ve spoken closely, but we’ve each taken our own decisions.” May has presided over a series of meetings on airline security recently, Slack said. The measures are a precaution and affect 14 airlines: British Airways Plc, Monarch, Thomas Cook, Thomson Airways Ltd., Turkish Airlines, Pegasus Airlines, Atlas Global, Middle East, Egypt Air, Royal Jordanian, Saudia, EasyJet Plc, Tunisian and Jet2.com.
