Meanwhile back in the US, the US Park Police (USPP) has defended its forceful clearing of protesters for a controversial Trump photo-op on Monday.
In a statement, the agency accused “violent protestors” of “throwing projectiles including bricks, frozen water bottles and caustic liquids”.
It denied that tear gas was used and said officers instead “employed the use of smoke canisters and pepper balls”.
As my colleague Oliver Holt pointed out in our earlier live blog, that statement does not tally with multiple reports on the ground that day. This nearly-two hour video from Reuters shows a peaceful protest pushed back.
An investigative reporter in DC, Nathan Baca, also picked up a canister at the scene that does appear to cause irritation.

When @usparkpolicepio says they didn’t use “CS or CN” tear gas, technically that’s correct. “OC” gas cannisters used instead. Causes same tears, tight breath and comes out green. This is not a smoke canister. I picked this off the street after it was launched at us Monday. pic.twitter.com/UuGJy0A6cr
