Washington, Jan 4, SPA -- Secretary of State Hillary Clinton said instability in Yemen posed a global threat and pledged on Monday to plug any holes in U.S. security procedures after a Christmas Day airline bombing attempt, according to Reuters. Clinton, in her first comments since the attempted Dec. 25 attack on a Detroit-bound plane sparked sharp criticism of the Obama administration"s counter-terror policies, said she would discuss additional steps with Obama"s security cabinet this week. "With respect to what happened with the terrorist on the plane coming into Detroit, we are not satisfied," Clinton told reporters following a meeting with visiting Qatar Prime Minister Hamad bin Jassem al-Thani. "So we will be meeting with the president tomorrow to go over our international reviews, to hear what others in our government also have concluded and to take whatever additional steps are necessary," she said. White House officials have conceded the Christmas Day bomb plot exposed errors but have played down the need for a top-to-bottom overhaul of the U.S. security system.--SPA 23:27 LOCAL TIME 20:27 GMT www.spa.gov.sa/734731
