Sania Mirza shot back at Veena Malik in a series of tweets.

A bitter Twitter war broke out between tennis star Sania Mirza and Veena Malik on Monday after the Pakistani actress questioned the sports icon -- married to Pakistan cricketer Shoaib Malik -- over parenting.

After a video was circulated on twitter, showing Sania Mirza's son Izhaan with his parents and some members of the Pakistan cricket team, Veena Malik asked why she had taken her nine-month-old son to a "sheesha place". Sheesha, a tobacco pipe, could be "hazardous" for the child, Veena Malik commented.

"Sania, I am actually so worried for the kid. You guys took him to a sheesha place isn't it Hazardious? Also as far as I know Archie's is all about junk food which isn't good for athletes/Boys. You must know well as you are mother and athlete yourself? (sic)" she tweeted on Monday.

Sania Mirza shot back saying she cares about her son a "lot more than anyone else does". On Veena Malik's apparent dig at Shoaib Malik's "junk food" habits, Sania Mirza's reply was: "I am not Pakistan cricket team's dietitian nor am I their mother or principal or teacher."

Veena,I hav not taken my kid to a sheesha place. Not that it's any of your or the rest of the world's business cause I think I care bout my son a lot more than anyone else does :) secondly I am not Pakistan cricket team's dietician nor am I their mother or principal or teacher https://t.co/R4lXSm794B — Sania Mirza (@MirzaSania) June 17, 2019

Retweeting a video shared by Veena Malik, which is no longer available, Sania Mirza said the video was shot without permission.

The Twitter spat got ugly after Veena Malik claimed she was blocked by the tennis star who, according to Veena Malik, also deleted a tweet during this exchange where she apparently referred to a magazine cover featuring the Pakistani actress.

Have some guts & don't delete ur tweets.Fortunately the technology has progressed so much that people can't deny their acts.Oh the magazine's cover u mentioned had morphed images.Also I can bringup all the controversies U have ever had bt I would rather not divert the discusion. pic.twitter.com/8qednFvEBz — VEENA MALIK (@iVeenaKhan) June 17, 2019

"Dearest Bhabhi, Attacking someone personally and reaching new heights of being low will not take you anywhere. Love, Veena Malik," the Pakistani actress wrote in another tweet.

Before Veena Malik's Twitter attack, Sania Mirza and Shoaib Malik were targeted by many on social media who shared pictures and claimed that the couple were partying with the Pakistan cricket team a day before the India-Pakistan cricket match on Sunday, which Pakistan lost.

The Pakistan Cricket Board in a clarification said the photos of the players dining and partying were actually not from the eve of the game. "The cricketers did not violate their curfew," a PCB spokesperson was quoted by Pakistan newspaper Dawn.
