The group "Fighting Xenophobie"-Fighting Racism, has admitted carrying out the attack by throwing Molotov cocktails at the building.....

Do you happen to know this group's French name? I'm wondering if they have any links to American groups opposing Trump such as Refuse Fascism.

They're called Kombattre La Xénophobie (Fight Xenophobia): https://newsradiotvmeliiran12.blogspot.com/2017/04/le-pen-campaign-hq-in-paris-targeted-by.html: "A group calling itself 'Kombattre La Xénophobie', or Fight Xenophobia, later claimed responsibility for the attack in a telephone call to the AFP news agency."
