So my father tried to get the police on the phone, but perhaps terrified by the rising tide of armed extremism that had already claimed the lives of so many Algerian officers, they didn't even answer.
Also versuchte mein Vater  die Polizei zu erreichen, aber vielleicht entsetzt durch  den flutartigen Anstieg des bewaffneten Extremismus,  der schon das Leben so vieler Polizisten gefordert hatte, hoben sie nicht einmal ab.
