Chancellor Angela Merkel has criticized German state TV for broadcasting the reading of a poem mocking the Turkish president Recep Tayyip Erdogan, which her spokesman said she believed was "deliberately offensive."
Merkel's spokesman Steffen Seibert said on Monday that the chancellor discussed the poem in a weekend telephone conservation with Turkish Prime Minister Ahmet Davutoglu.
German comedian Jan Boehmermann read the poem in a programme broadcast by ZDF television first on Thursday and then repeated on Saturday.
Seibert said Berlin considered the poem to be defamatory, which was not permitted in Germany, adding that its contents were below the belt.
Earlier this month, Ankara reacted angrily to another piece of televized satire that poked fun at Erdogan, after it was aired by German state broadcaster NDR.
Ankara made its displeasure with the two-minute song known to Berlin by calling the German ambassador to Turkey to a meeting in the foreign ministry.
