London police said they arrested three men under the Terrorism Act early Saturday. The arrests were near the home of the publisher of a forthcoming book about the Prophet Muhammad (pbuh). London's Metropolitan Police said they were questioning three men aged 22, 30 and 40 who were arrested on suspicion of committing, preparing or instigating acts of terrorism. But there were no immediate details of what the men were suspected of doing. Police said two of the men were stopped in the street by armed officers in Lonsdale Square, north London, and that a small fire at a house in the square was related to the arrest, police said. The British news agency Press Association said the house was the home and office of publisher Martin Rynja. His company, Gibson Square, announced earlier this month that it would publish a novel about the prophet Muhammad and his child bride titled "The Jewel of Medina." The third arrest was made near a subway station in the Islington district, in the same area of north London as Lonsdale Square. The arrests were intelligence-led, police said, indicating that there was no suggestion that an incident was imminent. Four properties in London, including one in Lonsdale Square, were being searched, police said. Meanwhile, a second opinion poll has shown Britain's ruling Labor Party narrowing the gap on the Conservatives following its annual conference, with the gap down to nine points.

The single-figure difference is the lowest since April, the Guardian said. On Thursday, a YouGov poll for the Sun newspaper put Labour on 31 points, 10 points behind the Conservatives – half the gap in a similar poll the previous week. Prime Minister Gordon Brown is likely to take heart from the polls after a slew of surveys during the past few months suggesting Labour could be wiped out in the next general election due to be held before mid
