Washington ( CNN ) -- The Transportation Security Administration announced Sunday that it will begin enhanced screening procedures Monday on any U.S.-bound air passenger traveling through `` state sponsors of terrorism or other countries of interest '' such as Pakistan , Yemen and Nigeria . The TSA said in a statement announcing the new measures that `` effective aviation security must begin beyond our borders . '' A senior government official , not authorized to speak on the record , provided CNN with the full list of 14 countries that fall under the TSA 's `` countries of interest '' label -- which will automatically trigger the enhanced screening . The State Department lists four countries as those that sponsor terror : Cuba , Sudan , Syria and Iran . The other 10 countries of interest are Afghanistan , Algeria , Iraq , Lebanon , Libya , Nigeria , Pakistan , Saudi Arabia , Somalia and Yemen , the government official said . Another source , a senior State Department official who could not speak on the record due to the sensitive nature of the material , said the countries on the list are places `` where we have concerns , particularly about al Qaeda affiliates . '' The official said the State Department was heavily involved in compiling the list , along with Department of Homeland Security and other intelligence agencies . The State Department compiles the annual `` Patterns of Global Terrorism '' report , which details terrorism trends in countries around the world . Passengers from other countries could still face enhanced security for other reasons . Unlike many TSA security directives , this one does not have an expiration date and is intended to be `` sustainable and long term , '' although the TSA will continually evaluate the mandate in light of intelligence , a federal counterterrorism official told CNN . The TSA said any person flying into the United States who is `` traveling from or through nations that are state sponsors of terrorism or other countries of interest will be required to go through enhanced screening . '' The TSA did not elaborate on what those enhanced security procedures might entail . The directive was issued to domestic and international air carriers . In addition , the directive also keeps in place a mandate -- issued after an attempted Christmas Day terror attack on a U.S.-bound flight -- giving pilots discretion to prevent passengers from keeping pillows and blankets on their laps during certain international flights , the official said . Also retained is the option for pilots to limit movement in the cabin on those international flights . Federal authorities have charged Umar Farouk AbdulMutallab , 23 , of Nigeria , in connection with the failed Christmas Day attack on a flight between the Netherlands and Detroit , Michigan . Authorities have said he tried to detonate explosives hidden in his underwear as the flight made its final approach to Detroit . The device failed to fully detonate , instead setting off a fire at his seat . CNN 's Mike Ahlers contributed to this report .
