( Cihan ) - Police determined that an A-3 bomb was used in Tuesday's blast in one of Ankara's busiest commercial quarters.
One suspect was detained at the Ulus district and the investigation into the case continues.
According to the last information, six people died and 100 were wounded. Sixteen of the wounded are reported to be in serious condition. The blast occurred just before a bus arrived at the bus stop near the location and this coincidence in timing prevented a higher number of casualties.
An official from security directorate state that there was not a crater at the scene which indicates that the explosion might have been caused by a suicide bomber.
The police are also looking through the security camera footages of the shopping center.
The explosion took place at around 6.50 p.m. when a bomb went off outside of a shopping center in the downtown district of Ulus.
The faзade of the building was almost destroyed and its windows were blown out as well as the windows of nearby buildings.
Witnesses claimed that a bomb left at the bus stop located just in front of the building caused the explosion.
The number of injured was relatively higher since it occurred during the rush hour when people were leaving their offices.
Chief of Staff Yasar Buyukanit, Ankara Governor Kemal Onal, Turkish Police Chief Oguz Kaan Koksal and several ministers were among top Turkish officials visiting the scene later in the evening.
No groups have claimed the responsibility for the blast yet, however, it resembles Nov. 2003 blasts claimed by the Turkish cell of Al Qaeda, which killed over 60 people. The outlawed Kurdistan Workers Party (PKK) has also carried out similar bombings in the past.
