ATHENS — Greek counterterrorism officers have uncovered eight parcel bombs resembling those sent last week to the German finance minister in Berlin and to the Paris offices of the International Monetary Fund, a police official said on Tuesday.

The devices were discovered on Monday during a search of the Hellenic Post’s main sorting office, north of Athens, according to a police spokesman, Theodoros Chronopoulos. “The packages were destined for European countries,” he said, calling them “similar” to the ones sent to the German finance minister, Wolfgang Schäuble, and to the I.M.F.’s offices.

According to reports in the Greek news media, which Mr. Chronopoulos did not confirm, the packages intercepted at the Athens sorting office were addressed to European Union officials and to multinational companies. The targets reportedly included the leader of the eurozone group of finance ministers, Jeroen Dijsselbloem, who coordinates meetings on Greek bailout talks, and an unidentified official of the European Central Bank, one of Greece’s three main international creditors.

European Union finance ministers meeting on Tuesday in Brussels to discuss issues including tax policy were made aware of the parcel bombs, but they did not interrupt their talks. “Certainly, we are following these developments with concern,” Valdis Dombrovskis, a vice president of the European Commission, said.
