British parliament under possible terror attack. Ten injured

The UK parliament is in lockdown after an apparent multiple terror attack with at least ten injuries.  Several people were struck by a vehicle on Westminster Bridge. The vehicle carried on driving towards Parliament and crashed through the railings into the yard. At the same time, an assailant entered Parliament, stabbed a policeman and was quickly shot by armed police. Parliament was suspended by the Speaker and members were ordered to stay in place. A helicopter ambulance is evacuating injured on Westminster Bridge where at least 10 people were injured. Fifteen ambulances are on hand outside the House. A police officer bundled Prime Minister Theresa May out of the House.  Downing Street is also under lockdown. Police are treating the incident as a terrorist attack. Counter-terror teams are sweeping the Houses of Parliament and grounds.

There is initial speculation that a single assailant may have carried out both attacks. If so, the incident has been contained. If there were two, the second terrorist is on the run.
