“Turkish police have apprehended more suspects in connection with the bomb attack on a bustling pedestrian avenue in Istanbul that killed six people and wounded several dozen others, bringing the number of people in custody to 50, Turkey's justice minister said Tuesday. Sunday's explosion targeted Istiklal Avenue — a popular thoroughfare lined with shops and restaurants — and was a stark reminder of bombings in Turkish cities between 2015 and 2017 that crushed the public's sense of security. Turkish authorities blamed the attack on the outlawed Kurdistan Workers' Party, or PKK, as well as Syrian Kurdish groups affiliated with it. The Kurdish militants groups have, however, denied involvement. Police carried out raids in Istanbul several hours after the blast and detained 47 people, including a Syrian woman who is suspected of leaving a TNT-laden bomb at Istiklal. Police said the woman, identified as Ahlam Albashir, had crossed into Turkey from Syria illegally and has admitted to carrying out the attack. On Tuesday, Justice Minister Bekir Bozdag said the number of suspects in custody has increased to 50, but did not provide details.”
