Greek police use stun grenades on protesters during Merkel visit

ATHENS, Oct 9 (Reuters) - Greek riot police fired stun grenades and pepper spray to push back protesters rallying on Tuesday against visiting German Chancellor Angela Merkel.

Thousands of Greeks defied a protest ban to march on parliament during the visit, Merkel's first since the euro zone debt crisis erupted in Greece three years ago.
