At least 11 other people were injured, five seriously, when Israeli forces raided the Rafah refugee camp early on Wednesday, according to witnesses and Palestinian medical sources.
The teenager, Muhammad Hamdan, was killed after suffering injuries caused by shrapnel of a tank shell.
Israeli military sources said there had been a “massive exchange” of gunfire and Palestinian resistance fighters had been hit. There were no reported casualties other than the teenager.
Occupation forces were apparently carrying out an operation targeting tunnels allegedly used to smuggle weapons in from Egypt, claimed Israeli military sources.
