(BBC) Two women have been arrested on suspicion of terrorism offences following a Met Police appeal.
The suspects, aged 29 and 44, came forward to a police station in south London on Monday after they recognised themselves in the appeal pictures.
They are currently being held in custody at a police station in west London on suspicion of inviting support for a proscribed organisation.
The force is continuing to appeal for help identifying a third woman.
She was seen on social media at a pro-Palestine protest in Whitehall on 14 October, with an image of a paraglider on her top, the Met said.
