Five Israeli human rights groups said it was "incomprehensible" for the Israeli government to claim that it had met its obligations to increase the flow of aid in Gaza. 

Gisha and four other organizations petitioned the Supreme Court of Israel to demand that the government specify what measures the executive branch is taking to step up aid deliveries to the Palestinian territory.

After an initial hearing in April, the court asked the Israeli government to answer follow-up questions before a fresh hearing scheduled for Sunday.

In a second update provided to the court this week, the government maintained it was going "above and beyond" its obligations in facilitating the entry of aid into the Gaza Strip.

The five rights groups rejected the Israeli government's position on a Friday in a letter published by Gisha.

"It is inconceivable that the respondents, who admit to not having even the faintest idea about the extent of the aid required for residents of the Gaza Strip, are claiming that they have fulfilled their obligations — and even beyond," the groups said.

They said the shortages evident inside Gaza indicated "that the respondents are not meeting their obligations, not to the required extent nor at the necessary speed."

According to the Israeli Defense Ministry body responsible for Palestinian civil affairs, COGAT, more than 6,000 trucks entered the besieged territory last month. It described the deliveries as "a great surge in the amount of humanitarian aid going into Gaza."
