Mitt Romney had to have his facts corrected by the moderator during the second US presidential election debate.

The Republican candidate accused President Barack Obama of taking two weeks to call the attacks on the US embassy in Libya, in which four Americans died, an act of terror.

Mr Romney said the President had put fundraising first, claiming he had flown to Las Vegas and Colorado for political events. He said: "I think these actions taken by a President and a leader have symbolic significance and, perhaps, even material significance."

President Obama responded by saying: "The day after the attack, Governor, I stood in the Rose Garden and I told the American people and the world that we were going to find out exactly what happened, that this was an act of terror and I also said that we were going to hunt down those who committed this crime."

But Governor Romney reasserted his claims, saying: "It took the President 14 days before he called the attack in Benghazi an act of terror."

The moderator was then forced to interject, correcting Governor Romney, saying: "He did in fact, sir. He did call it an act of terror."
