A three-year-old girl was killed by Israeli forces in Gaza on Sunday, according to local sources inside the Palestinian territory.

Ahed Tareq al-Bayouk was reportedly playing near her family’s tent in Mawasi, Rafah, southern Gaza, when she was shot.

The Israel Defense Forces said in a statement that it was “not aware of a strike” but would “conduct an additional review” as more information was provided.

Ahed al-Bayouk’s death appears to have taken place on the Palestinian side of the so-called Yellow Line, behind which Israeli troops agreed to withdraw as part of the first phase of a US plan to end fighting in the region.
