The Turkish government says it has detained a large number of people tied to the deadly suicide bombings, but many questions still remain. Nathan Frandino reports.
Outside a hospital in Ankara, Mehmet Ali Altun is waiting for his sons to recover. They were there on Saturday when twin suicide bombings struck a pro-Kurdish peace rally, killing at least 97. Altun says one son saw the suspected bomber. (SOUNDBITE) (Turkish) FATHER OF THREE MEN WOUNDED THE IN BLASTS, MEHMET ALI ALTUN, SAYING: "This guy had two bags, one on his back and one in his hand. He blended within the crowd and my boy felt something was wrong. He told me that it was as if somebody whispered to me that 'this guy is a suicide bomber." A makeshift memorial is now growing at the blast site. Mourners have been paying tribute with red roses and photos of victims, while waiting for answers. Turkey's government says Islamic State is the prime suspect, but there's been no claim of responsibility. Deputy Prime Minister Numan Kurtulmus says a large of number of people has been detained. (SOUNDBITE) (Turkish) DEPUTY PRIME MINISTER, NUMAN KURTULMUS, SAYING (AUDIO ENDS OVER SHOTS OF PEOPLE LISTENING/WIDE OF KURTULMUS AT PODIUM): "I don't want to give any numbers. We have worked meticulously on all the possibilities, usual and unusual suspects. And in order for us to get an acceptable outcome, any speculation should be avoided for the time being." Government opponents meanwhile have blamed President Tayyip Erdogan. Protests have broken out, with many accusing the state at best of intelligence failings... and at worst complicity. The government - already facing a growing Kurdish conflict at home - denies the accusations.
