Bomb explosion in Manama, Bahrain

(Reuters) - An explosion shook the Bahraini capital Manama on Thursday, damaging two cars, the Interior Ministry said, about a week before a scheduled Formula One Grand Prix race in the Gulf Arab state which has drawn daily protests.

 The ministry gave no further details in its Twitter message, but Al Arabiya television said the blast was caused by a gas container thrown among cars on a street in Manama.
