unveiled the hypocritical countenance of supporters of inhuman and heinous terrorist acts,” Iranian president said in a message on Tuesday.

On October 27, a bomb attack targeted a bus carrying Iranian pilgrims to a holy shrine in Baghdad to mark the major Muslim holiday of Eid al-Adha.

The terrorists had reportedly attached a sticky bomb to the vehicle in the Taji area, north of the capital.

The explosive device reportedly detonated around 300 meters from a police checkpoint. The blast left five Iranian nationals dead and 12 more injured.

Ahmadinejad's office called on the officials in charge to take advantage of all capacities to indentify the perpetrators behind the killing.
