A man was captured after killing his sister and her two children in the southern city of Antalya.

Bayram D., who lives with his mother in a village in Antalya, woke up early on Monday and went to a room where his pregnant sister and her twin children were sleeping after locking his mother up in her room. He slit their throats and fled the home before security forces captured the 29-year-old suspect.

The suspect was reportedly suffering from a mental illness and had attempted to kill himself four times and attempted to stab his mother once.
