Terror suspect Usama bin Laden may be planning new attacks in the next few weeks if he can mobilize resources, senior British officials said Friday.

``I understand he is preparing for high-impact terrorist attacks in the coming weeks, if he's able to,'' Europe Minister Peter Hain told the British Broadcasting Corp., citing intelligence reports.

``We've got to track him down. We've got to stop him,'' he said.

Foreign Secretary Jack Straw echoed the warning, saying there could be attacks in Britain. Police have warned that London could be a major target for attacks like those carried out in the United States.
