Iranians Condemn the Attack by the Basij on the British Embassy

We as Iranians and activists of the Green Movement, strongly condemn the attack by the Basijis on the British embassy (many others are condemning the attack via Twitter, Facebook, Google Plus and etc. )
We ask the media, such as Guardian, to stop calling the embassy attackers "students". They are just some paid Basijis, as we can see in this picture.Or do they look like students?

This is the first video which shows pro regime supporters attacking the British embassy:

What would be a possible goal of the attack?
Bahman Kalbasi, New York, UN Correspondent of BBC TV News, Persian Service tweeted:

Attack on UK embassy: another sign that powerful elements in Tehran welcome more isolation for #Iran in order to strengthen their hand.
