Greece has opened an investigation into the apparently accidental death of an Israeli couple.

Haim and Esther Giron were en route on a private Cessna C182 from Haifa (Israel) to Samos (Greece). However, for an unknown reason, the plane exploded over the sea shortly before landing on the island of Samos.

Haim Giron was a former deputy director of the Israeli Ministry of Communications. In that capacity, he was due to testify for the prosecution on allegations that former Prime Minister Benjamin Netanyahu had "sought and obtained unwarranted advantages from media moguls in Israel in order to benefit his personal affairs."
