Eleven people were hurt in two demonstrations in Gaza on Tuesday, Palestinian medical sources said.

The Palestinian sources said the 11 were hurt by Israeli fire. That could not independently be confirmed.

The Israeli military said the demonstrations took place close to the fence between Gaza and southern Israel in prohibited areas. The demonstrators tried to reach the security fence, and the Israel Defense Force fired warning shots, an IDF spokesman said.

The incident took place in a zone near the fence where explosives have been planted in the past and where two Israeli soldiers were killed last week, according to the spokesman.

Separately, a 15-year-old boy was reported shot to death at the Rafah airport in Gaza, said Muawiya Hassanein, director of ambulance and emergency services in Gaza. Additional information about the reported death was not immediately available.

The Israeli military said it was unaware of any Palestinians who were injured or killed in or near Rafah.

In the first demonstration, three Palestinians near the Bureij refugee camp in central Gaza were wounded while participating in a demonstration to mark Land Day, an annual day of protest by some Palestinians against Israeli policies they consider to be discriminatory.

The three were headed toward a border area when they were wounded, Hassanein said.

Near the town of Khan Younis, meanwhile, eight demonstrators were hurt during Land Day demonstrations, Palestinian medical sources said. The accounts could not independently be verified.
