Doctor speaks of 'hundreds of casualties' in Bahrain
Hundreds of people have been injured in clashes in Bahrain, according to a doctor who spoke to the BBC by phone from the Gulf state.
He also said that soldiers and police had seized ambulances and appeared to be firing on anyone in their path, but that it was impossible to identify where those responsible for the violence were from.
On Monday troops from neighbouring Gulf states were sent to Bahrain to help deal with continuing anti-government protests. The king of Bahrain has also declared a three-month state of emergency.
To protect his identity the doctor is named only as 'Abdul'.
