A Foreign Office spokeswoman said:

We have closely followed events in Belarus leading up to, and during, the Freedom Day demonstrations. We are concerned over the actions of the law enforcement agencies in Minsk. A large number of citizens, activists and journalists appear to have been arbitrarily and indiscriminately detained.

There is no justification for the use of force or intimidation against those exercising their right to peaceful protest. We urge the Government of Belarus to respect and uphold the right to freedom of association, assembly and expression. We further call on the government of Belarus to release all those peaceful protesters still detained.
