Police searched several houses near Glasgow International Airport on Sunday in connection with a fiery attack on its main terminal and a foiled car bomb plot in London. In a nationally televised interview, Britain's new prime minister, Gordon Brown, said the country was clearly dealing with terrorists, according to a report of the Associated Press. Three suspects were in police custody Sunday and a fourth man was under guard in a hospital after a flaming Jeep crashed into a Scottish airport on Saturday and two car bomb plots were foiled in central London on Friday.
