Turkey on Thursday launched an air attack on Iraqi Kurdistan in response to the killing of a Turkish diplomat in the region, the country's defence minister said.
The Turkish vice consul to Iraq's autonomous Kurdish region was shot dead Wednesday in the local capital Arbil. Police sources said two other people were also killed.
There was no claim of responsibility for the shooting, but many Iraqi experts have pointed to the probability that the Turkish separatist Kurdistan Workers' Party (PKK), which Ankara considers a terrorist group, was behind the attack.
"Following the evil attack in Arbil, we have launched the most comprehensive air operation on Qandil and dealt a heavy blow to the (PKK) terror organisation," defence minister Hulusi Akar said in a statement.
Targets such as "armaments positions, lodgings, shelters and caves belonging to terrorists" were destroyed. "Our fight against terror will continue with increasing determination until the last terrorist is neutralised and the blood of our martyrs will be avenged," he added.
The Kurdistan Democratic Party (KDP), which now leads the regional government, enjoys good political and trade relations with Turkey.
But Turkey has been conducting a ground offensive and bombing campaign since May in the mountainous northern region to root out the PKK which has waged an insurgency against the Turkish state since 1984.
Earlier this month, the PKK announced that one of those raids killed senior PKK leader Diyar Gharib Mohammed along with two other fighters.
A spokesman for the PKK's armed branch denied the group was involved in Wednesday's shooting.
