A police officer and people are seen walking next to the scene of a car bomb attack in central Anatolian city,Kayseri
VON PRESS Middle East: Television pictures showed that the bus had been reduced to a smoldering wreck by the impact of the blast, as wounded were taken to waiting ambulances.
Deputy Prime Minister Veysi Kaynak said in televised comments that the attack in Kayseri was "unfortunately similar" to last weekend's strikes in Istanbul.
The army said that the bus -- carrying low-ranking privates and non-commissioned officers -- was attacked after leaving the commando headquarters in the city.
The bus was owned by the municipal transport authorities in Kayersi but was transporting the soldiers who had taken permission to go to a local market for the day, the Dogan news agency reported.

Turkey has seen a spate of deadly bombings in a bloody 2016 blamed both on Takfiri terrorist and Kurdish militants.
In June, 47 people were killed in a triple suicide bombing and gun attack at Istanbul's Ataturk airport.
Another 57 people including 34 children were killed in August in a terrorist attack by an ISIS-linked bomber at a Kurdish wedding in the southeastern city of Gaziantep.
Kurdish militants have twice struck with bombings that killed dozens in Ankara in February and March.
The attacks have come with the civil war still raging in neighboring Syria, where Turkey is staging its own incursion to force extremists and Kurdish militia from the border area.
Turkey is also still reeling from a failed July 15 coup blamed on the US-based Islamic preacher Fethullah Gulen that has been followed by a relentless purge of his alleged supporters from all state institutions.
Kayseri is well west of the southeast of the country that has been hit by months of deadly fighting between the outlawed Kurdistan Workers Party (PKK) and the security forces.
There was no immediate indication of who was behind the latest attack.
The Turkish military has stepped up operations against the PKK after a fragile ceasefire broke down in the summer of 2015. Since then, there has been a dramatic surge in violence that shows no sign of ending.
Last week's double bombing in Istanbul, which targeted police after a match of the Besiktas football club, was claimed by the Kurdistan Freedom Falcons (TAK) seen as a radical offshoot of the PKK.
The attack in Istanbul prompted a sharp response from Erdogan, who vowed Ankara would "fight the scourge of terrorism right to the end".
"They should know that they will not get away with it ... They will pay a heavier price."
