Not much of a surprise here and one would imagine this also will include extra checks for people who visited countries on the list. The Guardian:
The US transportation security administration announced that everyone flying into the US from or through these countries would go through "enhanced screening" at airports.
The list includes Nigeria, home of Umar Farouk Abdulmutallab, the failed suicide bomber who tried to blow up a Detroit-bound passenger plane using an explosive device hidden in his underpants. It also includes Yemen, where it is claimed he was trained.
The other "countries of interest" are Afghanistan, Algeria, Iraq, Lebanon, Libya, Pakistan, Saudi Arabia and Somalia, and four countries the US regards as state sponsors of terrorism: Cuba, Iran, Sudan and Syria.
