According to Afghan authorities, the blast in Kabul targeted a Nevruz celebration.
"We learned with deep sorrow that a terrorist attack perpetrated in Kabul today during Nawroz celebrations resulted in loss of lives of many Afghan brothers and sisters and left many others wounded," the Turkish Foreign Ministry said in a statement.
"We condemn this heinous terrorist attack," it added.
The ministry wished a "speedy recovery to the wounded" and also offered "condolences to the friendly government and the brotherly people of Afghanistan".
The Nevruz festival on March 21 has been celebrated for more than 18 centuries across Anatolia and Asia.
The March 21 festival is celebrated mainly in Iran, Afghanistan, India, and Turkic republics such as Azerbaijan, Caucasus countries, Albania and Macedonia.
The festival -- which is considered as a forerunner of spring -- is a UN-recognized international cultural day.
