Deadly bombings spark fear in Turkey ahead of elections

The Islamic State of Iraq and Syria (ISIS) has emerged as the leading suspect behind Saturday's terrorist attack in Turkey's capital, Ankara that killed 97 people--the worst the country has faced in its modern history.

Turkey's prime minister said Monday that they are close to identifying one of the suicide bombers.

The twin bomb attacks came just ahead of national elections next month. Turkey, which used to be held up as a rare example of stability and democracy in the Middle East, is now looking increasingly unstable, reports CBS News correspondent Holly Williams.

Hundreds of people were holding a rally for peace Saturday when two explosions left carnage on a city street.

"Arms and legs were flying up into the sky," said one witness. "Two of my friends were killed, but I survived."

The attack follows an upsurge in violence between the Turkish government and militants from Turkey's Kurdish minority.

Sparked by a suicide bomb that killed more than 30 people in July, hundreds have been killed on both sides, and the Turkish government has launched air strikes on Kurdish militant camps.

As Kurdish politicians tried to lay flowers at the scene of the attack Sunday, there was a confrontation with police, who said investigators were still working at the site.

The Turkish prime minister said that Kurdish militants and ISIS were possible suspects. Around 40 suspected ISIS militants have been arrested since the attack, but it is still unclear if there is any link to the bombings, and nobody has claimed responsibility.

Many of the mourners believe the Turkish government is to blame because, they say, it's stirred up unrest ahead of national elections next month.

Just three weeks away from an election in which Kurdish voters could play a decisive role, the mood is tense, and many fear more violence.
