Interior Minister Ali Yerlikaya says one of the two attackers blew himself in front of the ministry building in Ankara.

Ali Yerlikaya said two attackers were responsible for the explosions in front of the ministry building. One of them blew himself and other was “neutralised”, the minister said.

Al Jazeera’s Sinem Koseoglu, reporting from Istanbul, said the explosion happened around 9:30am.

“The security measures have been tightened around the parliament building and around the interior ministry building that are in close proximity.

“Parliament is resuming after its summer break. All parliamentarians, including the president [Recep Tayyip Erdogan], were expected to be at the Parliament in the afternoon around 2pm,” she said.

The Al Jazeera correspondent said that it is too early to say who might be behind the attack.

The attack comes as Turkish authorities have been carrying out operations against ISIL (ISIS) members.
