The Turkish presidency's communications director Fahrettin Altun on Wednesday hit out at Meta-owned Instagram, accusing the platform of "impeding people from publishing messages of condolence for the martyr Haniyeh".

Ismail Haniyeh, the political chief of the armed Palestinian Islamist group Hamas and a close ally of Turkish President Recep Tayyip Erdogan, was killed in Tehran on Wednesday in an attack blamed on Israel.

"This is a very clear and obvious attempt at censure," Altun said on X.
