Israel's army launched new air strikes Sunday against Hamas positions in Gaza and closed the fishing zone around the Palestinian enclave in response to rockets and firebombs sent into Israeli territory.
The strikes came after a week of heightened tensions, including clashes on Saturday evening along the Gaza-Israeli border, the army said.
Dozens of Palestinian "rioters burned tyres, hurled explosive devices and grenades towards the security fence and attempted to approach it," the Israel Defense Forces (IDF) said in a statement.
Long simmering Palestinian anger has flared further since Israel and the UAE on Thursday agreed to normalise relations, a move Palestinians saw as a betrayal of their cause by the Gulf country.
Over the past week Israeli forces have carried out repeated night-time strikes on targets linked to the Islamist group Hamas, which controls the Israeli-besieged Gaza Strip.
The army says they were carried out in response to makeshift firebombs attached to balloons and kites which have been sent into southern Israel, causing thousands of fires on Israeli farms and communities.
There were 19 such Palestinian attacks on Saturday alone, according to Israeli rescue services.
In response, "IDF fighter jets and aircraft struck a number of Hamas military targets in the Gaza Strip," the army said, adding that among the targets hit were a Hamas "military compound and underground infrastructure".
Early Sunday the Israeli army said two nore rockets had been fired into Israel from Gaza and intercepted by its Iron Dome defence system.
"In response, our Air Force just struck Hamas terror targets in Gaza, including a military compound used to store rocket ammunition," it said.
Total fishing ban
Following rocket and incendiary balloon attacks earlier this week, Israel on Wednesday slashed Gaza's permitted coastal fishing zone from 15 nautical miles to eight, a punitive move often used by Israel in response to Gaza unrest.
Following Saturday's clashes and rocket-fire, Israel's military decided "to entirely shut down the fishing zone of the Gaza Strip, immediately and until further notice, starting this morning (Sunday)," a military statement said.
Israel has also closed its Kerem Shalom goods crossing with the Gaza Strip.
Despite a truce last year backed by the UN and Egypt, the two sides clash sporadically with rockets, mortar fire or incendiary balloons.
The Gaza Strip has a population of two million, more than half of whom live in poverty, according to the World Bank.
The Israeli army said Hamas "is responsible for all events transpiring in the Gaza Strip and emanating from it, and will bear the consequences for terror activity against Israeli civilians".
