Turkey's prime minister says authorities investigating the blasts at a peace rally that killed 99 people have detained 10 more people suspected of links to Kurdish rebels and the Islamic State group.

Ahmet Davutoglu said Thursday the suspects were detained in the last two days.

Some detentions were linked to two suspects who were detained on Wednesday for posting tweets about a bombing in Ankara a day before the suicide bombings occurred. The government said the two have links to the Kurdish rebels.

Some analysts are skeptical about claims of Kurdish rebel involvement because many Kurdish activists many Kurdish activists attended Saturday's rally, and some were among the dead and injured.

Turkey has banned reporting on the investigation, which media groups have slammed as censorship.
