Police in Turkey say a small bomb has exploded near the office of Prime Minister Recep Tayyip Erdogan in Ankara, wounding one person.
The blast March 5 came ahead of a cabinet meeting at Erdogan's office.
Turkish state-run television said the blast was caused by a percussion bomb, and one government employee was slightly wounded.
Police were searching the area for possible other explosive devices.
Percussion bombs make a loud noise, but cause little if any damage.
The blast came after a remote-controlled bomb in Istanbul wounded 15 police and one civilian on March 1. It is not clear who carried out the latest blasts.
Kurdish rebels, fighting for autonomy in Turkey's southeast, as well as radical leftist and Islamic militants, have all carried out bomb attacks in Turkey previously.
