(Adds police saying McDonald’s was attack target)
ATHENS, July 3 (Reuters) - A homemade bomb exploded outside a McDonald's MCD.N restaurant in Athens early on Friday, shattering windows but causing no injuries, police said.
The 2 kg (4.4 lb) dynamite bomb smashed windows of the fast-food restaurant, which was the target of the attack and not an adjacent government tax office building as initially thought.
The bombing was the latest in a string of attacks against domestic and foreign businesses in Greece since widespread rioting in December last year, sparked by the police killing of a teenager and fuelled by discontent at economic slowdown.
“We are certain now that McDonald’s was the target,” a senior police official said on condition of anonymity. “We estimate that extremist group Revolutionary Struggle may be behind the attack,” the official told Reuters.
Revolutionary Struggle, one of Greece's most militant guerrilla groups, earlier this year claimed responsibility for two bloodless bomb attacks against Citibank C.N branches in Athens.
Friday’s bomb, which was placed under a ramp for people with disabilities, exploded at 0137 GMT, police said in a statement. There were two warning calls but no claim of responsibility.
In a separate incident later on Friday, attackers threw gas canisters at the entrance of the Institute of Immigration Policy in central Athens, causing damage but no injuries, police said. (Reporting by George Georgiopoulos and Harry Papachristou; Editing by Ingrid Melander and Charles Dick)
