Negotiators are close to striking a deal on compensation for Turkish victims of a deadly Zionist raid on a Gaza aid flotilla four years ago, a Turkish official said Monday.

The May 2010 Zionist assault on the Turkish ship the Mavi Marmara while it was in international waters on its way to Gaza sent relations between the occupation entity and Turkey to an all-time low.

Talks on compensation for the nine Turks killed in the raid eventually began in March 2013 after Zionist entity extended a formal apology to Turkey in a breakthrough brokered by US President Barack Obama.

"We are close to an agreement" to settle the compensation issue, a Turkish official told AFP on Monday.

Foreign Minister Ahmet Davutoglu acknowledged on Sunday there had been a "momentum" in talks in order to bridge the gaps.

"It would not be correct to provide a timeframe on such (delicate) issues but I can say that serious progress has been made in recent meetings," Davutoglu told Turkish television.

"A historic step was taken with the apology... Now a second step will be taken with the compensation," he said.

"We are going through a period where the relations are the closest to normalization after Mavi Marmara".
