Washington, August 26 (RHC)-- The Pentagon says the United States and Turkey have finalized details of a plan to include Turkey in the U.S.-led coalition battling the self-proclaimed Islamic State.

Turkey entered the fight against ISIL last month, opening up an airbase to the United States and beginning airstrikes against alleged militants in Syria.

Turkey has also stepped up attacks against the dissident group the Kurdistan Workers’ Party, known as the PKK, inside both Turkey and in northern Iraq, where the PKK has been fighting against ISIL for more than a year.

In Washington, Pentagon Press Secretary Peter Cook announced the plan for Turkey to join the coalition aerial campaign against ISIL on Tuesday.
