Palma de Majorca (Spain), July 30 (DPA) Suspected militants of the armed Basque separatist group ETA Thursday targeted the Spanish tourist island of Majorca during the high holiday season, killing two police officers in a bomb blast.

Police sources confirmed that two officers of the paramilitary Civil Guard were killed and several people were injured in the blast.

The two victims were believed to have been inside a car which exploded in Palmanova on the western coast, one of the most popular tourism sites on Majorca, where hotels were full at the time.

The bombing was the second attributed to ETA within a little more than 24 hours.

A bomb had been attached to the underside of a police patrol vehicle, according to unconfirmed reports.

The explosion occurred near a police building, a post office, a firefighters' station and a hotel.

The Spanish royal family traditionally spends its summer holidays on Majorca.
