The driver of a train sustained moderate injuries Sunday morning, when a blast hit his train between Rehovot and Yavneh at around 7:30 A.M.

Police said they suspected that the cause of the explosion was a device placed on the tracks, but that they were not ruling out a technical fault.

It was not initially clear whether the blast was inside the driver's cabin or on the tracks.

Israel Radio reported that the source of the blast was an explosive device on the tracks and that investigators were checking whether it had been detonated by remote control or when it was struck by the train.

The train was travelling from Binyamina, near Hadera, to Ashdod in the south.

The driver was taken to Kaplan Hospital in Rehovot for treatment.

Several weeks ago four people were milldy wounded when a bomb was detonated on the train tracks near Lod.
