New Delhi: In a shocking incident, a 22-year-old newly married woman was allegedly murdered by her husband and her sister in southwest Delhi on Thursday.

"Pooja had been married to 23- year -old Rahul Solanki for one-and-a-half months, when she discovered that her husband was having an affair with her 20-year-old sister Rinky", said a senior police officer.
