Officials say truck bombs targeted the offices of two Kurdish political parties in northern Iraq, killing at least 28 people and injuring 148.
Shalal Abdul, the mayor in the town of Tuz Khurmatu, said the attack happened around noon on June 9.
Abdul said a suicide bomber first detonated his truck after driving it into a checkpoint leading up to the offices of the Patriotic Union of Kurdistan (PUK) and the nearby Kurdistan Communist Party.
When people gathered to help the wounded, a second truck bomb exploded.
It was the second double bombing targeting Kurdish offices in as many days.
On June 9, a suicide bomber followed by a car bomb explosion targeted PUK offices in Jalula in ethnically mixed Diyala Province.
Another suicide car bombing hit an army checkpoint south of Baquba on June 9, killing two soldiers.
