"Everyone's connected to Hamas, everyone gets a salary from Hamas, and all the activists trying to challenge us and breach the border are Hamas military wing activists".
Violence spiked again on Friday when thousands of protesters returned to the border.
Reporters Without Borders have accused Israel of "deliberate shooting" of journalists in Gaza, after one photographer was killed gunfire another seven reporters were injured at a protest.
Witnesses said Murtaja was over 100 meters (yards) from the border, wearing a flak jacket marked "press" and holding his camera when he was shot in an exposed area just below the armpit. Madi was killed east of Gaza City by an expanding dum-dum bullet, the ministry said.
The report further referred to concerns by the Israeli army sources that in case of many Palestinian casualties, the worldwide community might renew diplomatic pressure on the regime.
The Great Return March is a 45-day protest festival that will culminate on May 15 - Nakba Day, also known as the day of catastrophe - when Palestinian Arabs were thrown out of their land and their houses were destroyed by Israel in 1948, leading subsequently to their being caged into the West Bank and Gaza.
Palestinian news agency Maan said that an Israeli tank fired twice towards the Strip, however the Israeli military said it only used small arms fire.
The Hamas-linked Palestinian Information Center's twitter feed said the shots were fired at peaceful protesters in the border region near Khan Younis.
They added that "several attempts have been made to damage and cross the security fence under the cover of the smokescreen".
Observers sought an global investigation into the war crimes and said that the use of lethal force by the Israeli Defence Forces (IDF) against unarmed civilians and those protected under worldwide law is a clear violation of the Fourth Geneva Convention.
"Whoever flies a drone over (Israeli) forces, over our soldiers -- we won't take any chances".
This is a view shared by media watchdog Reporters Without Borders (RSF). The deaths brought to at least 31 the number of Palestinians killed by Israeli fire since last week.
However, Israel says Hamas itself is to blame for the humanitarian crisis because of its refusal to disarm and renounce violence.
The tweet was later deleted.
The European Union and U.N. Secretary-General Antonio Guterres have called for an independent investigation, which Israel has rejected.
