ISTANBUL , Turkey ( CNN ) -- Turkish authorities have arrested 13 people in connection with blasts that killed 17 people in Istanbul last week , Interior Minister Besir Atalay said Saturday . Video from last week 's bombing in Istanbul shows bloodied people being loaded into ambulances . Of those arrested , 10 were sent to judicial court , Atalay said in a televised news conference . He described the attack as the `` work of the bloody separatist group , '' but did not identify a group by name . No one has claimed responsibility for the blasts , which went off within minutes of each other in Istanbul 's crowded Gungoren community . About 154 people were wounded , state-run Anadolu news agency reported . Istanbul Gov . Muammer Guler , who called the blasts `` an act of terror , '' said last week that the explosive devices were placed 15 meters ( 49 feet ) from each other . The first was a stun grenade that was detonated to draw attention before the second blast went off , he said . The other , a bomb , had been placed in a trash can . Turkey -- a candidate for European Union membership -- has pushed its anti-terror campaign on multiple fronts . Tensions between Turkey » and Kurdish rebels have risen over the Kurdistan Workers ' Party 's increasing attacks and Turkey 's subsequent crackdown . The rebels , known as the PKK , have waged a decades-long battle for an autonomous Kurdish region in Turkey 's southeast . Last month , 86 people -- including former military officials , journalists , politicians and businessmen -- were indicted on charges of being involved with an alleged terror group called Ergenekon , which aims to topple the Turkish government . The arrests and indictments dramatize the sharp and serious political tensions between the country 's Islam-rooted ruling party -- the Justice and Development Party , or AKP -- and its outspoken critics from the nation 's secularist population .
