The newspaper made those remarks in its lead editorial today, titled "Stop the Bloodbath."
Michael Lynk, the Special Rapporteur on the situation of human rights in the Palestinian territory, says Israel is guilty of "blatant excessive use of force," in breach of international human rights laws.
Saying Israel was denying rights of expression and assembly, Lynk issued a statement on Tuesday calling for "true accountability for those in military and political command who have ordered or allowed this force to be once again employed at the Gaza fence."
Israeli officials say that Hamas has used the protests to cover terrorist activities, and to distract Palestinians from "their failures as a governing body."
Hamas leader Yahya Sinwar has joined at least one of the weekly protests against the blockade; he was seen again on Monday. His public appearances prompted new comments from Israel's Public Defense Minister Gilad Erdan, who told the Ynet News site, "We need to go back to targeted killings, and they need to go back to hiding underground and fearing for their lives, not organizing the masses to carry out terror attacks."
Erdan said, "It's time for the heads of Hamas to pay a personal price for organizing these terror attacks."
On Monday afternoon, the White House blamed the death toll on the Palestinian Islamist group Hamas.
Principal deputy press secretary Raj Shah said, "Hamas bears the responsibility," adding, "Look, this is a propaganda attempt. I mean, this is a gruesome and unfortunate propaganda attempt. I think the Israeli government has spent weeks trying to handle this without violence, and we find it very unfortunate."
Shah reiterated the White House's position that Israel has the right to defend itself.
When asked about possible peace talks between Israelis and Palestinians and the timing of the most recent White House contact with Palestinian leaders Shah said, "Well, I don't honestly have an answer for you on that. I'll get back to you."
