In May 2007 , there was a bombing in Ankara that killed 6 and injured 121 people . The Turkish government alleged the PKK was responsible for the bombing . On 4 June , a PKK suicide bombing in Tunceli killed seven soldiers and wounded six at a military base . Tensions across the Iraqi border also started playing up as Turkish forces entered Iraq several times in pursuit of PKK fighting and In June , as 4 soldiers were killed by landmines , large areas of Iraqi Kurdistan were shelled which damaged 9 villages and forced residents to flee . On 7 October 2007 , 40 – 50 PKK fighters ambushed an 18-man Turkish commando unit in the Gabar mountains , killing 15 commandos and injuring three , which made it the deadliest PKK attack since the 1990s . In response a law was passed allowing the Turkish military to take action inside Iraqi territory . Than on 21 October 2007 , 150 – 200 militants attacked an outpost , in Dağlıca , Yüksekova , manned by a 50-strong infantry battalion . The outpost was overrun and the PKK killed 12 , wounded 17 and captured 8 Turkish soldiers . They then withdrew into Iraqi Kurdistan , taking the 8 captive soldiers with them . The Turkish military claimed to have killed 32 PKK fighters in hot pursuit operations , after the attack , however this was denied by the PKK and no corpses of PKK militants were produced by the Turkish military . The Turkish military responded by bombing PKK bases on 24 October and started preparing for a major cross-border military operation
