Israel did not agree to end its Gaza blockade as part of reconciliation with Turkey, and could clamp down even harder on the Palestinian enclave if security is threatened, a senior Israeli official said on Sunday.

"We did not agree to promise [Turkey] that under any condition we would continue to transfer all the things into Gaza and ease up on the residents of Gaza if there is shooting from there," Israeli national security adviser Yaakov Amidror told Israel's Army Radio.

"We do not intend to give up on our right to respond to what happens in Gaza because of the agreement with the Turks,” he added.

The news comes just two days after Israeli Prime Minister Benjamin Netanyahu “expressed apology” to the Turkish people for an Israeli operation which killed nine Turks aboard a Gaza-bound activist ship in 2010.

The Israeli leader said Tel Aviv has agreed to pay compensation to the families of the victims and that Israel and Turkey have agreed to work together to improve the humanitarian situation in the Palestinian territories.

The flotilla incident has been a source of mounting tension for almost three years. Turkey expelled the Israeli ambassador and severed military ties with Tel Aviv in protest against Israel’s refusal to apologize.  

Throughout the rift, Turkish Prime Minister Recep Tayyip Erdogan has routinely insisted that Israel end the blockade – a wish that Tel Aviv now says it is unwilling to grant.

However, Israel has agreed to relax the curbs on Gaza’s civilian imports and pledged to “continue to work to improve” Palestinians’ humanitarian situation.

Amidror was very clear, though, that Tel Aviv will not hesitate to reverse its concessions if necessary.

"If there is quiet, the processes easing the lives of Gazan residents will continue. And if there is Katyusha [rocket] fire, then these moves will be slowed and even stopped and, if necessary, even reversed," he said.

The reconciliation seemed to be a US bid to repair relations between Ankara and Tel Aviv. News of the apology came just after US President Barack Obama said that Erdogan and Netanyahu had spoken on the phone on Friday.

“I am hopeful that today’s exchange between the two leaders will enable them to engage in deeper cooperation on this and a range of other challenges and opportunities,” Obama said in a statement on Friday.

The move was also praised by UN: “Assisting Israel and Turkey in restoring their good relations had been a core objective of the secretary-general’s efforts in the aftermath of the May 2010 flotilla incident,” UN spokesman Marin Nesirky said in a Friday statement.

“Today’s announcement is an important and hopeful signal for stability in the region,” he added.
