(Adds police saying McDonald's was attack target)
ATHENS, July 3 (Reuters) - A homemade bomb exploded outside
a McDonald's 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 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.
