The woolwich attacks today are a disaster for all our communities, especially the Muslim community, esp Black and Brown communities, and especially for any viable united movement in this country against the imperialist policies of this government. The far-right white nationalist of the english defence league and other similar far-right formations were bound to use this incident to stoke up more divisions and violence in the interests of the british state, and this is what is going on now. There already reports of three mosques being attacked, and probably there are increased racist attacks and fights between Muslims and whites. It is very important that we all look out for each other against these attacks and any other dodgy moves by the media, police and intel services. - Sukant Chandan, Sons of Malcolm
English Defence League supporters have thrown missiles at police in Woolwich after a machete attack that left one man dead.
A group of between 75 and 100 men gathered at The Queen's Arms pub on Burrage Grove, where they sang nationalistic songs.
Sky News correspondent Alistair Bunkall, who is at the scene, said: "As soon as the EDL got into the town centre ... it became not only a lot harder for the police to try and contain anything, but also the aggression (increased) quite considerably.
"A few missiles have been thrown, glass bottles and the like. The police are trying to surround them and they've been charging them as well with batons."
It came after two men were arrested following separate attacks on mosques hours after the suspected terrorist incident in Woolwich.
A 43-year-old man is in custody on suspicion of attempted arson after reportedly walking into a mosque with a knife in Braintree, Essex.
Local MP Brooks Newmark said on this Twitter account: "Local mosque in Braintree attacked by man with knives and incendiary device. Man arrested. No one injured.
"Just met with leaders of local mosque in Braintree which was attacked this evening. Thanked local police for their swift response."
Essex Police confirmed a 43-year-old from Braintree had been arrested on suspicion of possession of an offensive weapon and attempted arson after the incident in Silks Way at 7.15pm.
Meanwhile police in Kent were called to reports of criminal damage at a mosque in Canterbury Street, Gillingham, at 8.40pm.
A spokesman said a man was in custody on suspicion of racially-aggravated criminal damage.
