Thilo Sarrazin: 'Forced marriages should be forbidden'

The controversial author Thilo Sarrazin has sparked a debate about Islam in Germany by saying Muslims are either "unwilling or unable to integrate" into Western society.

He says Muslim migrants must accept German laws, the constitution and the values of their new society. He thinks Germany has gone too far in trying to accommodate them.

He told the BBC's Gavin Hewitt that parents who do not send their children to school should be fined and forced marriages should be forbidden.
