Greek authorities have found makeshift bombs, explosives, hand grenades and thousands of bullets during a raid on a warehouse on the southern island of Crete, police said on Friday, the second such operation this week.
The explosive devices were ready for use, police said in a statement, adding that one person had been detained and was due to appear before a prosecutor.
Earlier this week, following a tip-off, police in Crete confiscated rifles, shotguns, knives, drugs and more than 8,000 bullets from an apartment and a storage room owned by a 36-year-old man, who was arrested.
Illegal gun ownership is relatively common in Crete.
