For the 1rst Time, the State which has notoriously done the most for -and exploited the most - ISIS Islamist Terrorists' emergence and extension from its Borders outwards : Turkey, was hit by New US President Donald Trump's Anti-Terror Measures, Starting by Prohibiting Turkish Airlines' import of Computers and Tablets, etc., inside the US, unless they are Baned from the Passengers Planes' Cabin, and closed in a distinct Cargo.
Thus, Turkish AIrlines was put in the Same List with, f.ex., Saudi Airlines, Qatar Airlines, Kuwait Airways, Emirates and Etihad Airlines, Middle- East Airlines, etc.
Almost at the Same Time, Theresa May's Government in the UK, took Similar Anti-Terrorist Measures, also vis a vis Turkey and certain Other such Risky Countries, including Saudi Arabia, etc., concerning All AirFlights Directly connected with them.
France, Canada, and/or other Countries are, reportedly, considering whether to take some SImilar Measures.
"Ataturk' Istanbul's Airport (IST) in Turkey, is a key Target of 2017 ANti-Terrorist Measures, (which are Open-Ended), including also Hamad International Airport (DOH) in Qatar, King Khalid International Airport (RUH) in Saudi Arabia, Kuwait International Airport (KWI) in Kuwait, etc.
It's through Turkey that the most ISIS' and other Islamist Terrorists' "Jihadists", and/or their Weapons or Oil Smugglers, Human Traffickers, etc., have, notoriously, being coming and going, during the last 5 or 6 Years, at least.
