Turkey ? Turkey and Iraq agreed Tuesday to try to root out a Kurdish rebel group from northern Iraq, but Iraq’s prime minister said his parliament would have the final say on efforts to halt the guerrillas’ cross-border attacks into Turkey.

Turkey has threatened to send troops into northern Iraq unless Iraq or the United States cracked down on the separatist Kurdistan Workers Party, or PKK, which seeks greater autonomy for mostly Kurdish regions of southeastern Turkey. For decades, the group has maintained bases in Iraq’s Kurdish mountains.

The proposed counterterrorism agreement is aimed at forcing Iraq to commit itself officially to fighting the rebels.
