Turkey's parliament went into secret session this week to debate sending troops to invade and occupy northern Iraq for security purposes.
More than 30,000 people have been killed in the confrontation between the Kurdish Workers Party (PKK) and the Turkish army – about 400 last year alone, according to Turkey's Human Rights Association.
Onur Oymen, the deputy chairman of the Opposition Republican People’s Party (CHP), said: "Northern Iraq is the only place in the world where a terrorist group can operate without being pursued."
"If the Iraqis and the US are not prepared to take action over this, then we must."
