David Cameron says he knows all too well how millions of Americans felt on September 11, 2001. His wife, Samantha, then pregnant with their first child, had flown into New York the day before and he spent 5 frantic hours back in Britain trying to contact her, recalled the British prime minister, speaking at a joint press conference with President Obama. Samantha, he says, was caught up in "chaotic scenes" a few miles from Ground Zero.
"I will never forget the 5 hours of trying to get hold of her, and she will never forget the New Yorkers she met that day or the sense of solidarity that she felt that day and we have felt ever since that day," Cameron said. "Today, as we come up to its 10th anniversary, we should remember the spirit of that city and the sympathy we feel with those who lost their loved ones." (Read more Obama visits Britain stories.)
