ANKARA, May 20: A woman was killed and one other person injured when a bomb went off in a cafe in the heart of the Turkish capital Ankara on Tuesday, officials said.

Prosecutor Ahmet Mutlu told journalists the blast had been caused by a bomb after he inspected the site, Anatolia news agency reported.

The device went off in the toilet of the cafe immediately after a young woman entered it, the NTV news channel said, while police sources confirmed that the dead person was a woman.

NTV speculated that the woman may herself have placed the bomb in the toilet.
