A woman killed herself by consuming poison after administering the same to her sons at Jameenoothukuli near Pollachi.

According to police, neighbours of the woman, Vidya, grew suspicious as she did not open the door for a long time on Friday morning.

When they peeped through the window, they saw Vidya and her sons lying with froth coming out of their mouths.

A family dispute is said to be behind the suicide, police said.
