Yes, she was formerly a presenter for the Israeli Channel 14 and before that the Jerusalem Bureau for CNN:

"It was later reported by at least one major TV news network that the reports of babies being beheaded had been "confirmed" by a spokesperson for the Israeli prime minister's office.
This was subsequently attributed to Tal Heinrich, a freelance news anchor who appears to have been drafted in by Benjamin Netanyahu's office on 8 October to assist with media relations in the wake of Hamas's attacks a day earlier.
The only available public statement on the matter from Ms Heinrich at the time of writing was an interview she conducted with LBC on Wednesday, in which she was asked about the claims.
Ms Heinrich, who was quoted by LBC as a spokesperson for Mr Netanyahu's office, said: "Toddlers, babies, I can tell you some of them... yes, heads were cut off. This is what we are hearing from... soldiers on the ground who dealt with the bodies."
Replying to a later post on X linking to a story citing her comments, she said on Wednesday evening: "Please note: We said that these reports are based on testimonies of soldiers."
The lie was started by an IDF soldier and then broadcast by the Israeli Channel i24. Then repeated all around the World without being fact checked.
It's played a part in why governments lent their unconditional support to the Israeli response (even Trump mentioned burnt babies numerous times in the last 2 weeks)
The reason it set of alarm bell was that it was so similar to the The Nayirah Testimony which had been used to manufacture consent for the first Gulf War. :
"The Nayirah testimony was false testimony given before the United States Congressional Human Rights Caucus on October 10, 1990, by a 15-year-old Kuwaiti girl who was publicly identified only as Nayirah at the time, and presented herself as having been a volunteer nurse at a Kuwaiti hospital at the time of the Iraqi invasion of Kuwait. In her testimony, which took place two months after the invasion, she claimed to have witnessed Iraqi soldiers taking premature babies out of incubators in a maternity ward before looting the incubators and leaving the babies to die on the floor. Nayirah's statements were widely publicized and cited numerous times in the United States Senate and by American president George H. W. Bush to contribute to the rationale for pursuing military action against Iraq. Her portrayal of Iraqi war crimes was aimed at further increasing global support for Kuwait against the Iraqi occupation during the Gulf War, which resulted in the expulsion of Iraqi troops from Kuwait by a 42-country coalition led by the United States.
