'At least 27 killed' in Ankara explosion

At least 27 people have been killed after an explosion in the Turkish capital Ankara, officials said. The governor's office said at least 75 others were wounded in the blast that occurred near the city's main square. The explosion is believed to have been caused by a car bomb that went off close to some bus stops. The explosion came just three weeks after a suicide car bombing in the capital targeted buses carrying military personnel, killing 29 people. A Kurdish militant group which is an offshoot of the outlawed Kurdish rebel group, the Kurdistan Workers' Party, or PKK, claimed responsibility for that attack. Police sealed off the area and pushed onlookers and journalists back, warning there could be a second bomb.
