On Feb. 17, Ankara witnessed its first suicide attack carried out with a moving vehicle. The attack targeted a military shuttle bus, killing 29 people, mostly military personnel. In a column I wrote after that attack, I asked if that was just the beginning.
Twenty-five days later, about a kilometer (half a mile) from the scene of the Feb. 17 bombing, there was another suicide bombing, again with a moving vehicle. However, this attack, at the central square of the city, was against civilians. The March 13 attack killed 37 people, wounded 125 and shook the country to its core.
