Turkish warplanes have attacked suspected rebel Kurds in northern Iraq for a second day. The airforce confirmed the raids, and said all its planes returned safely. The bombing runs are believed to have lasted for about an hour. No casualties were reported on the ground.The Kurdistan Workers’ Party, or PKK, is based in the mountains along Iraq’s northern border. It is branded a terrorist organisation by Turkey, Europe and the United States, but not by Iraq. Reports in Turkey, however, say Baghdad may be close to outlawing the group as well, putting pressure on the semi-autonomous Iraqi Kurdistan region to dismantle the PKK’s bases there. Some 40,000 people have been killed since 1984 when the PKK launched its armed campaign for a Kurdish homeland in southeastern Turkey.
