Two men have been arrested over alleged terrorism offences, Scotland Yard said.
The latest terror arrests allegedly relate to a planned overseas plot
Officers detained the men, aged 25 and 39, on suspicion of the "commission, preparation or instigation of acts of terrorism" under the Terrorism Act.
Police say the arrests came after raids at two separate homes in north-west and west London early on Tuesday morning.
The allegations are reportedly related to offences being planned overseas. The men are being held in custody at a London police station.
