Jerusalem (CNN) -- Israel declared a German poet persona non grata Sunday in an unusual move that follows a wave of fury over a controversial poem.

Published in the German paper Süddeutsche Zeitung on Wednesday under the title "What needs to be said," the poem by Gunter Grass accused Israel of planning a preemptive strike against Iran in order to "extinguish the Iranian people." It said Israel's "atomic power endangers" world peace.

The poem also criticized the German government for supplying Israel with a submarine capable of sending destructive warheads "where the existence of a single nuclear bomb is unproven."

The 84-year-old Grass, who won a Nobel Prize in literature in 1999, is now unwelcome in Israel, the government announced.
