On Friday, Palestinian paramedic Razan al-Najjar was shot dead by Israeli soldiers near the Gaza-Israel separation fence.
Thousands of people gathered in Gaza on Saturday to attend the funeral of Najjar, protesting her death as a crime against humanity.
The 21-year-old paramedic was reportedly shot in the chest while trying to medically assist injured protesters near the border. She was wearing her white paramedic's uniform.
Najjar's father held her blood-stained medical vest while marching in her funeral procession, according to The Washington Post.
Following her death, Nickolay Mladenov, the U.N. Middle East envoy, said "Israel needs to calibrate its use of force and Hamas need to prevent incidents at the fence. Escalation only costs more lives," in a tweet.
"Medical workers are #NotATarget!" he added.
More than 115 people have been killed since protests dubbed the Great March of Return began in March and over 13,000 more have been injured.
"Gone but not forgotten"
"Without weapons, we can do anything"
The paramedic had plans to announce her engagement to Izzat Shatat, a volunteer ambulance worker, towards the end of Ramadan.
The Israeli army said it is "investigating Razan's death".
Earlier this year, The New York Times spoke to Najjar, one of the only female medical volunteers to treat medical emergencies during the protests.
"We have one goal — to save lives and evacuate people," she said in the video interview.
"And to send a message to the world: Without weapons, we can do anything."
