US President Barack Obama on Tuesday vowed to defeat the al-Qaeda terrorist network and hit them anywhere in the world from where they are plotting attack against the US. President Obama said this in his first public statement after the foiled attempt by an al-Qaeda operative to blow up a US plane on Christmas Day with more than 270 people on board. In his nationally televised remarks from Hawaii, Obama said that a full investigation has been launched into this attempted act of terrorism, and the US will not rest until it finds all who were involved and hold them accountable.<br/><br/>Terror suspect Umar Farouk Abdulmutallab, 23, has been charged with trying to destroy a Detroit-bound US plane. He is currently lodged in a federal prison. Meanwhile, al-Qaeda has claimed its role in the failed attempt to blow up the US-bound plane. Maryland-based SITE Intelligence Group, which monitors radical Islamist forums and websites, said the al-Qaeda in the Arabian Peninsula made such a claim on Monday in a communiqu’ issued to fundamentalist forums.<br/>
