Sixteen soldiers were killed when a roadside bomb laid by Kurdish militant group Kurdistan Workers Party (PKK) exploded as two armoured vehicles passed, the Turkish army said in a statement on Monday.
Its warplanes bombed 23 Kurdish insurgent targets on Monday, the day after the militants staged what appeared to be their deadliest attack since the collapse of a two-year-old ceasefire.
The army also said six soldiers were wounded in the attack, but that none of them were in critical condition.
