A 42-year-old was aborted while swimming in the Rhine on Sunday and has been missing since then.

Her 41-year-old husband, who was in the water with her, was rescued by a jet ski driver, the police said on Sunday.

Accordingly, the couple had gone into the Rhine from a sandbank near Biebesheim in the afternoon.

Both were drifted away and pulled further and further into the middle of the river.

The woman sank into the water and was no longer seen.

Extensive search measures with several boats, helicopters and divers were initially unsuccessful.
