A female suicide car bomber who killed at least 35 people in Ankara had links to Syrian Kurdish rebels, the interior ministry said in a statement on Tuesday.

The ministry, which identified the bomber as Seher Cagla Demir, born in 1992, said she had been affiliated with the outlawed Kurdistan Workers' Party since 2013 and then "crossed into Syria and received terror training in the YPG terrorist organisation."

The People's Protection Units or YPG is a Syrian Kurdish militia that Ankara regards as a terror outfit.
