Turkish authorities seized on Friday a bus carrying 500 kilograms of highly explosive material. According to Turkey's Anadolu Agency, authorities said the bus was seized at the road leading into Ankara, noting that the material was imported from Switzerland by a Turkish petrochemical firm. The material was brought into Turkey in a manner that contradicts legal measures and has raised much suspicion, said the authorities that launched an investigation into this matter, especially that the load was supposed to be delivered in Izmir, not Ankara. The material was more powerful than the one found in a truck that was seized two days ago.
