A 14th explosive package, this one addressed to the French Embassy in Athens, was found Thursday as the Greek authorities struggled to contain an elaborate, if not particularly destructive, bomb plot that has been unfolding for four days, The New York Times reports.

Most of the relatively mild explosive devices, in letters or parcels, were sent to foreign embassies in Athens. But one, addressed to the German chancellor, Angela Merkel, was found in her office’s mailroom; another, addressed to the Italian leader, Silvio Berlusconi, was intercepted en route. A letter bomb addressed to the French president was seized. The tension in the Greek capital is such that police cordoned off the Greek Parliament building in central Athens for two hours Thursday after a small package without a return address sparked an alert. The area was reopened after the police established that the package contained nothing but books.

On Wednesday, the authorities suspended the shipment of foreign-bound letters and small packages for 48 hours. On Thursday, spokesmen for the Greek police and civil aviation authority said that such shipments would resume Friday morning as scheduled.

The package addressed to the French Embassy was returned by officials there to a courier service in the Athens area. Bomb disposals experts detonated it there.
