Frankfurt: German police and firefighters are clearing a section of Frankfurt around the convention center to defuse a World War II-era bomb that was discovered during recent construction work.
Authorities say some 2,700 people are being asked to leave their homes as they cordon off the area as a precaution to defuse the 500-kilogram (1,100-pound) bomb.
Buses and trains through the area were also shut down and bomb experts were expected to get to work on the bomb about noon Friday.
