The Israeli authorities said that Israeli military came under fire from Gaza, followed by a tank, the Israeli military opened fire on the checkpoint crews "Izzedine al-Qassam" in Northern Gaza.
An Israeli military statement, apparently referring to the same incident, said that the army returned fire after shots were fired at its soldiers from a Hamas post in the northern Gaza Strip, next to the border with Israel.
"The resistance can not allow the occupation to impose a policy of bombing sites and targeting fighters without paying the price", a Hamas statement said.

Hamas said in response that "Israel is responsible for this entire escalation", and warned that "the resistance will not accept the [Israeli] policy of attacking its positions and fighters without Israel paying a price".
Israel killed two Hamas fighters following shooting attacks on its soldiers, spurring threats of revenge from the terrorist group that runs the Gaza Strip.
Sources confirmed that Murjan and al-Silawi were members of the Izz al-Din al-Qassam Brigades, the armed wing of the Hamas movement.
The tension in Gaza has been high since the Palestinians launched massive anti-Israel rallies in March, known as "the Great March of Return", which demanded the lift of the blockade Israel has imposed on Gaza since 2007.
Two months after its construction began, earlier this week, Israel's Ministry of Defense released first footage of the sea barrier it is building along the country's border with Gaza. At least 160 Palestinians have been killed by Israeli fire, including at least 120 in protests near the border fence.
