Ankara: A bomb exploded on Monday near the offices of Turkish Prime Minister Recep Tayyip Erdogan in Ankara, lightly injuring one person.

The device, which was in a small plastic bottle, went off at around 0730 GMT (1300 IST), 20 metres from the building in the central Kizilay district, one and a half hour before a cabinet meeting to be headed by Erdogan.

Police blocked access to the blast zone -- the entrance to the parking lot of the supreme court of appeals, fearing a second explosion.

The injured was a court employee, it added.

Security guards at Erdogan's office also rushed to the scene.

The blast followed a remote-controlled bomb attack in Istanbul last week near Erdogan's ruling party headquarters, which wounded 15 police officers and one civilian.

In September, a powerful bomb rocked the centre of the capital Ankara, killing three people and wounding at least 15 others.

A bomb blast in May last year injured eight people near a bus stop in Etiler, an upscale district in Istanbul.
