The underground Turkish Communist Party claimed the responsibility for the blast in one of the Istanbul offices of the Turkish ruling party “Justice and Development” Party led by Premier Recep Erdogan.

The communists issued an e-email statement they organized the blast in one of the offices as protest against workers’ deaths in factories and mines, the Turkish Atilim website reports.

A few days ago the underground communists set off a bomb at one of the offices of the Turkish Nationalistic Party.
