The PKK terrorist organization's latest attack targeting civilians late Sunday killed 37 people and injured another 125. Among the dead are believed to be two suicide bombers, a male and a female, both having links to the terrorist group. The police detained 11 suspects across the country and questioned the family of one of the attackers. The suicide attack is the third in Ankara in the last six months. The previous attacks on Feb. 17 and Oct. 10 last year killed 29 and 102 people respectively.

Here are the heartbreaking stories of six victims of the latest terror attack.
