Manama: Bahrain has increased its security arrangement for next week`s Formula One race after a series of explosions, including a gas cylinder blast that set a car ablaze in the Gulf nation`s financial district.

Although the attacks caused no major injuries or damage to property,

it sent a message that militants could step up violence before Sunday`s F1, the premier international event in the kingdom.

Bahrain has experienced more than two years of unrest between the Sunni-led government and majority Shiites.

Bahrain`s Interior Ministry says the four blasts happened in quick succession late yesterday, ending with the gas canister explosion inside a stolen car in Bahrain`s Financial Harbor.

Bahrain says it will provide “adequate” security to protect fans and F1 teams.
