The fishing zone was restricted to 6 nautical miles earlier this week following a rocket fired from Gaza that landed off the coast of Israel.
There was no specific date for when the crossings and the fishing zone would reopen.
Saturday’s rocket barrage came less than a day after two militants from Hamas’ armed wing, the Qassam Brigades, were killed in an Israeli strike on Hamas posts in Gaza.
A serious escalation
Israel launched airstrikes Friday after two Israeli soldiers were wounded by sniper fire along the Gaza border.
Two other Palestinians died in Gaza Friday, according to the Palestinian Ministry of Health, with both men succumbing to their wounds after being shot by Israeli troops during protests along the Gaza fence, according to health officials.
This is the first serious escalation between Israel and Gaza militants since the Israeli election
almost a month ago.
In the run-up to that election, Egypt succeeded in mediating an agreement between Israel and Hamas, the militant group that runs Gaza, following an exchange of rockets and airstrikes in March.
The agreement, though never publicly acknowledged by Israel, included measures aimed at loosening the restrictions imposed on Gaza’s 2 million inhabitants.
Recent pronouncements by Hamas officials have suggested growing frustration that Israel has not moved fast enough to fulfill its pledges, including allowing the transfer of millions of dollars of extra funding from Qatar.
The upturn in violence comes as Israel is preparing to mark Independence Day next week and host the Eurovision Song Contest the following week.
Analysts say Israel’s Prime Minister Benjamin Netanyahu
would much prefer those events to occur in a state of calm rather than one of open conflict.
On Saturday evening, the UN’s Special Coordinator for the Middle East Peace Process, Nickolay Mladenov, announcing renewed efforts with Egypt to restore calm, called on all parties to immediately de-escalate or risk a conflict with “grave consequences for all.”
