The Gaza border remains volatile as the Israeli soldiers opened fire from across a border fence killing four Palestinians.
Among those killed was a 15-year-old boy as well.
Reports indicate that more than 150 have even been wounded.
This came about as several thousand people in blockaded Gaza staged a fourth round of weekly protests on the border with Israel.
Some of the activists threw stones toward the fence or flew kites with flaming rags dangling from their tails.
The latest deaths raised the total number to 32 of the Palestinians killed by Israeli troops in protests since late March.
The Israeli forces are continuing their crackdown despite the fact that international community has criticized it.
Hamas says the protests are aimed at breaking a crippling border blockade that was imposed by Israel and Egypt after the Islamic militant group overran Gaza in 2007.
Earlier on Friday, Israeli military aircraft had dropped leaflets urging Palestinians to stay away from the fence and warning that they endanger their lives if they follow Hamas directives.>
