MANAMA, Bahrain (AP) _ Bombs gutted one shop and damaged two others early Sunday at a chic shopping arcade in the heart of Bahrain's capital. There were no reported injuries.

The Bahrain Shopping Complex was closed when the bombs exploded at about 2 a.m. A security source at the scene said it was not immediately known how many bombs were planted.

``They must have used very sophisticated explosive devices,'' said the security source, who spoke on condition of anonymity. ``They could not have been bigger than cigarette boxes for them not to be detected when planted.''

The shopping complex is an annex of the luxury Sheraton hotel, a short distance from the prime minister's office and the ``diplomatic'' neighborhood that houses several ministries and many offshore banks.

``I have lost everything,'' said Khaled Shah Gilani, the owner of a music shop that was completely destroyed. ``I shall have to start all over again.''

Sunday's explosions were the latest in a series of bomb and arson attacks blamed by the government of this central Gulf Arab state on what it calls arsonists and saboteurs.

Unrest in Bahrain, a key Middle East financial center and home to a major U.S. Navy base, began in December 1994 with the Shiite Muslim-led opposition pressing the Sunni-dominated government for the restoration of a parliament suspended in 1975.

The dissidents also demand the release of hundreds detained during the unrest and better job opportunities.

Violence has escalated sharply in Bahrain this year: Three hotels were bombed, and restaurants, bank machines and other properties have been set afire. Hundreds have been arrested in the disturbances, and 27 people have been reported killed.
