The Israeli military said on Saturday it was investigating the apparent killing by its troops of a Palestinian nurse on Friday during protests along the Gaza border.
Health officials and witnesses said Israeli forces shot dead 21-year-old Razan al-Najar, a volunteer medic, as she ran towards the border fence, east of the south Gaza city of Khan Younis, in a bid to reach a casualty.
The Israeli military said Palestinian militants had attacked its troops along the border with gunfire and a grenade.
In a written statement on Saturday, the military said it would investigate al-Najar's death.
Thousands of people attended al-Najar's funeral in Gaza on Saturday, including some she had treated when they were wounded at previous border protests. Her body was wrapped in a Palestinian flag and carried through the streets on a stretcher by mourners.
"With our souls and blood we redeem you martyr Razan," cried mourners as the body was brought to her home for a last farewell before burial.
Residents said al-Najar was a popular figure at the protest sites and pictures depicting her as an angel circulated on Palestinian social media.
Her death brought to 119 the number of Palestinians killed in weekly demonstrations launched on March 30 in the Gaza Strip, an enclave controlled by the Islamist group Hamas and long subject to grinding Israeli and Egyptian embargoes.
