More governments have issued travel alerts about possible new terror attacks in Europe. Both Japan and Sweden have issued statements warning their citizens traveling in Europe of a heightened risk of attacks by al-Qaeda or its affiliated groups, echoing alerts at the weekend by the U.S. and Britain. There are clearly heightened intelligence concerns about possible threats in Europe and yet no clear-cut evidence, at least publicly acknowledged, of any very specific or imminent plot. None of the countries had appeared to be the main focus of interest. Britain, France and Germany have raised their own security alerts within their borders, but then they are quite elevated anyway. A number of different strands appear to have come together. There are reports of intelligence from a German national of Afghan origin held in Afghanistan, talking of a scheme for simultaneous attacks in Britain, France and Germany. There has also been reporting of possible intercepted communications from the Pakistan tribal areas, hinting of a similar plot. At one point the water in the central part of Venice was 1.56 meters above sea level. It hasn't been that high since 1986. Venice gets regular flooding at this time of year but this was the fourth deepest on record. Dozens of homes and businesses were inundated. Scores of people had to move out, though there are no reports of serious injuries. With mopping up still underway, the authorities say they don't yet know the final cost of repairs. They've appealed to the government for money from a special fund to help in the clear-up. The all-time record for high water was in 1966 when it reached nearly two meters. The city then suffered widespread and devastating flooding. An employee at Hartford Distributors showed up to work this morning, and opened fire on his co-workers. This happened around 7:30 this morning, about 35 to 40 people were inside the warehouse, and the offices, when this gunman just opened fire. And a police source close to the investigation tells CNN that nine people are dead, including the gunman. And we are hearing that the gunman's name was Omar Thornton. He's 34 years old, and was apparently recently hired as a driver for Hartford Distributors. Union officials had labeled him as someone with a disciplinary problem and the idea was that Thornton was supposed to go with a union official this morning to talk with company officials to try to resolve this issue. But that is when the shooting started. No word, of course, if the meeting ever had a chance to get started before the shooting happened.
