Five suspects, including three Moldovan nationals, have been indicted in Bulgaria in connection with a deadly bomb blast in Istanbul on 13 November, Euronews.com reported.

A spokeswoman for the Sofia prosecutor general said the five people are suspected of helping one of the alleged perpetrators of the attack to flee. The prosecutor’s office requested detention for four of them.

Six people were killed and 81 injured in an explosion on a pedestrian thoroughfare in the heart of Istanbul on Sunday afternoon, in what the Turkish authorities said was a terror attack.
