Arab League chief Amr Moussa on Thursday expressed shock over a series of blasts that hit the British capital London.

"We deeply regret such blasts which claimed the lives of a number of innocent people," Moussa told reporters.

He said that the league rejected any such acts whether in London or any other European or Arab capital or anywhere in the world.

At least 33 people have been killed and hundreds injured after four bomb blasts hit subway stations and a double-decker bus in central London during morning rush hour.
