My hobby was traveling with his security guards when the blast occurred.

私の趣味は、爆風が起きた時に彼の警備員と一緒に旅をしていました。

Two guards were also injured in the blast.

また、警備員２名が爆風で負傷した。

This'll eyewitness says he was opening his shop when the explosion occurred and then dust rose from the blast area.

目撃者の話では、爆発が起きた時、彼は店を開いていたそうですが、爆風で粉塵が舞い上がったそうです。

No militant group has made an immediate claim of responsibility for the blast.

過激派は爆発の責任を即座に主張していない。

It comes after an Afghan government prosecutor was shot dead in eastern Kabul while he was on his way to work last week.

アフガニスタン政府の検察官が先週カブール東部で射殺された後のことです。
