A bomb blast ripped through a restaurant shortly after noon yesterday, killing one woman and injuring 11. Police said four of the wounded were Americans from a cruise ship.

It was third bombing in five days on the French Caribbean island. The wave of violence began just before the first stage of local elections last Sunday. There was no immediate claim of responsibility for the blast at the L'Escale restaurant, The Associated Press reported.

Authorities said the dead man was Marie-Jose Aubery, 37, of Guadeloupe. Police identified the injured Americans as Mobena and Chester Ray and Marion and Jeanny Martz, all hospitalized with third-degree burns. Hometowns were not known immediately. Authorities said their cruise ship, the Amerikanis, arrived earlier from St. Thomas and many of its 618 passengers were ashore at the time of the blast.

The first round of local elections was held Sunday in Guadeloupe, other French overseas departments, and in France. The second round is scheduled for March 17. Reuter reported that the restauranteur was a member of the rightist National Front, which shared in a conservative victory in the first round.

In France yesterday, the front's leader, Marie Le Pen, threw support behind rival conservatives with a better chance of winning Sunday. His position came as a surprise. He had previously stated he would tell his candidates to stay on the ballot after the major opposition parties refused a pact.
