New Delhi, May 25 (IANS) In an shocking incident, a 27-year-old woman in south Delhi Friday killed her two infants - a boy and a girl - before committing suicide after killing her two children, police said.

Vineeta Katara, her daughter Harshita, 3, and son Arpit, 1 and a half were found dead in their residence at Deluxe Apartments at Chhattarpur in Mehrauli.

Police said that Deepak, a nursing student at All India Institute of Medical Sciences, had been questioned and investigation was under way.
