Two Palestinians including a teenage boy were killed and scores wounded by Israeli fire on Friday, Gaza health officials said, as weekly border rallies organized by the Islamic militant group that rules the territory continued.

The 13-year-old was fatally shot in the head and a 24-year-old man died of gunshot wounds to his leg and abdomen, the Gaza Health Ministry said.

More than 130 wounded were evacuated to hospitals for treatment, with at least three in serious condition, the ministry said. About 90 others received first aid.

The Gaza clashes reached their peak on May 14, the eve of the 70th anniversary of Nakba Day (the Day of Catastrophe), when the Israeli regime forcibly drove more than 760,000 Palestinians - now estimated to number nearly five million with their descendants – out of their homes.

This year’s anniversary coincided with the US embassy relocation from Tel Aviv to occupied Jerusalem al-Quds, a highly provocative move that infuriated Palestinians and intensified the protests.

Since 1948, the Israeli regime has denied Palestinian refugees the right to return, despite United Nations resolutions and international law that upholds people’s right to return to their homelands.

Israel has launched several wars on the Palestinian coastal sliver, the last of which began in early July 2014. The military aggression, which ended on August 26, 2014, killed nearly 2,200 Palestinians. Over 11,100 others were also wounded in the war.

The Gaza Strip has been under an Israeli siege since June 2007. The blockade has caused a decline in the standards of living as well as unprecedented levels of unemployment and poverty.

The Israeli regime denies about 1.8 million Palestinians  in Gaza their basic rights, such as freedom of movement, jobs with proper wages as well as adequate healthcare and education.
