A US congressman has warned al-Qaeda is actively recruiting US Muslims for violent attacks within the country.
Representative Peter King, a Republican, spoke at a House homeland security committee hearing into the "radicalisation" of US Muslims.
He said "homegrown radicalisation" was "part of al-Qaeda's strategy to continue attacking the US".
Critics say the hearing will feed anti-Islamic sentiment and have criticised Mr King for singling Muslims out.
A senior Democratic congressman warned the committee not to "blot the good name" of American Muslims.
Mr King, a New York Democrat, has said US mosques are a breeding ground for radical attitudes. BBC News
