Israel on Sunday barred German author Gunter Grass from entering the Jewish state, citing a poem in which he accuses Israel of plotting Iran's annihilation and threatening world peace.
"Interior Minister Eli Yishai declared Gunter Grass persona non grata in Israel," a statement from Yishai's office said.
"Gunter's poem is an attempt to fan the flames of hate against the state of Israel and the Israeli people," it quoted Yishai as saying.
In his poem "What must be said," the 84-year-old longtime leftist activist wrote of his concern that Israel "could wipe out the Iranian people" with a "first strike" due to the threat it sees in Tehran's disputed nuclear programme.
"Why do I only say now, aged and with my last ink: the atomic power Israel is endangering the already fragile world peace?" reads the poem, which was published on Wednesday in the daily Sueddeutsche Zeitung.
The poem sparked outrage in Israel, with officials from Prime Minister Benjamin Netanyahu on down criticizing Grass. Netanyahu on Thursday called Grass's poem "shameful."
"If Gunter wants to continue disseminating his distorted and mendacious works I advise him to do it from Iran where he will find a supportive audience," Yishai said on Sunday.
Israel's Foreign Minister Avigdor Lieberman also criticized the poem on Sunday, during a meeting with Italian Prime Minister Mario Monti.
He said it was an expression of the "cynicism" of some Western intellectuals, "who for their self-promotion and desire to sell a few more books are willing to sacrifice the Jewish people for the second time on the alter of deranged anti-Semites."
"We expect the European leadership to take a firm stance against such remarks made by public opinion leaders, and to not enable them," he added, warning that "we have already seen in the past how small seeds of anti-Semitic hate turn to a large fire that harms all humanity."
The poem has also sparked debate in Germany, where Foreign Minister Guido Westerwelle on Sunday penned a commentary that appeared to criticize Grass, without making explicit reference to the author.
"Germany has a historic responsibility for the citizens of Israel," he wrote in Bild Am Sonntag, Bild newspaper's Sunday magazine.
"To put Iran and Israel on an equal moral footing is not clever but absurd," he wrote.
Iran's deputy culture minister Javad Shamaqdari on Saturday praised Grass's poem, saying "it warns beautifully."
Grass, author of the renowned anti-war novel "The Tin Drum," sparked outrage in 2006 when he revealed, six decades after World War II, that he had been a member of the notorious Waffen SS.
Israel, the sole if undeclared nuclear power in the Middle East, has said it is keeping all options open for responding to Iran's nuclear programme, which it says is aimed at securing nuclear weapons, posing an existential threat to the Jewish state.
Iran has consistently denied that its sensitive nuclear work is aimed at making weapons.
