A pregnant woman has been killed by dogs while walking her own dog through a forest in northern France, investigators say.
Pilaski was six months pregnant when she died.

Animal activist Brigitte Bardot has addressed to Elisabeth Borne, French minister for ecological transition, requesting her to cease all hunts immediately: "You have a duty to operate instantly".
But the French hunting association insisted there was no evidence of "the involvement of hunting hounds in the death of this woman". "When I looked down into the precipice, the ravine, I saw around 30 dogs coming towards me so I pulled back", Pilarski's partner, Christophe, told BFMTV, adding that she was nude and had been "partially devoured".
