"Such despicable acts are in no way acceptable"
"We expect these attacks to be ended immediately, without further loss of life and without causing a new spiral of conflict in the region," the Turkish Foreign Ministry said in a statement.
The ministry also expressed condolences to Palestinians.
At least 12 people were killed, including women and children, and 20 others were injured in airstrikes carried out early Tuesday in Gaza by the Israeli military.
The casualties were announced by the Health Ministry in Gaza.
