What we've heard so far from police about the incidentpublished at 11:25 British Summer Time

At 21:08 local time (02:08 BST) on Wednesday, police received multiple calls about a shooting outside an event at the Capital Jewish Museum in downtown Washington DC.
A man and a woman were found unconscious and not breathing at the scene, and later died.
The Metropolitan Police Department (MPD) have alleged that the shooting was committed by Elias Rodriguez, 30, of Chicago, who is being questioned in custody.
MPD Chief Pamela Smith says Rodriguez was seen pacing up and down outside the museum before opening fire with a handgun on a group of four people.
The suspect then went inside the museum, where he was detained. Police say he chanted "free, free Palestine" while in custody.
MPD are leading the investigation. The FBI says it is looking into "ties to potential terrorism or motivation based on bias-based crime or a hate crime".
