The U.S. government closes its embassy in the Middle Eastern country of Yemen, and that is because of security concerns. One official says that a group called al Qaeda in the Arabian Peninsula might be planning an attack against the facility. That same group said it was behind an attempted plot to set off an explosive onboard a plane heading to Detroit, Michigan. That took place on Christmas day. The suspect allegedly brought the explosives on the plane in his underwear. The plan failed when the device he tried to use didn’t detonate correctly. Some people have asked how the suspect made it past security. One U.S. official says it’s because of human error. President Obama has promised that everyone involved in the attack will be held accountable for it. But some critics argue that the president’s response to the situation hasn’t been fast enough, hasn’t been aggressive enough.
