Syrian security forces raided ISIS hideouts in Aleppo on Saturday, killing at least one terrorist and arresting others, the Interior Ministry said, the first time such an operation has been announced under the country's new Islamist rulers.

A member of the security forces was also killed, the statement issued by Interior Ministry spokesperson said. The security forces seized weapons, bombs and uniforms with the security forces' insignia.

A security source said the raids had targeted sleeper cells in four locations. One Islamic State terrorist had blown himself up, and another had been killed in clashes, the source said.
