If you are referring to the shellings in Northern Iraq.
Turkey has joined forces with Iran and now Syria against the Kurdish PKK because the U.S. has not been willing to address their repeated requests for assistance (U.S. caught in the middle, though this Kurdish group was labeled 'terrorists' by the U.S.). In fact Iran and Turkey have been doing this shelling of Kurdish strongholds for several months already.

On edit: thanks for the links.
