Turkey's foreign minister will visit Iran on Wednesday for talks on Tehran's disputed nuclear program, his ministry announced amid rising regional tensions.

Foreign Minister Ahmet Davutoglu will hold two-day consultations with his Iranian counterpart Ali Akbar Salehi about Iran's nuclear program as well as developments in Iraq and Syria, the foreign ministry in a statement.

Turkey will compensate the families of 35 civilians mistakenly killed in an airstrike meant for Kurdish rebels, the deputy prime minister said, even as he insisted that military officials followed proper procedures, including firing warning shots.

The airstrikes, guided by intelligence from drones and fired by Turkish F-16 jets, hit a group of Kurdish smugglers in northern Iraq last week. The loss of life was one of the highest single-day civilian death tolls in Turkey's decades-old conflict with the rebels.

Four workers were killed in an explosion at an army ammunition storage depot in central Turkey on Monday, state-run Anatolia news agency reported.

The blast occurred in a TNT warehouse in Yahsihan in the central province of Kirikkale, the town's local administrator Ahmet Ferhan Ozen told Anatolia.

Turkey's exports increased by a record 18.2 percent in 2011, reaching $134.6 billion, Economy Minister Zafer Caglayan said on Monday.

"This is a record in the history of the republic," the minister was quoted as saying by the Anatolia news agency.

Gaza's Hamas Prime Minister Ismail Haniya will Monday meet the head of an Islamic aid group whose Gaza-bound vessel was stormed by Israeli troops in 2010 in a raid that left nine activists dead.

Haniya, who is making his first trip abroad since Hamas rose to power in Gaza in 2007, will tour the Turkish passenger ship Mavi Marmara and meet relatives of the victims.

Turkish Prime Minister Recep Tayyip Erdogan held talks on Sunday with Gaza's Hamas prime minister Ismail Haniya and voiced his support for Palestinian reconciliation efforts, media reports said.

Haniya is in Istanbul as part of his first official regional tour since his Islamist movement seized power in the Palestinian enclave in 2007, the Anatolia news agency reported.

Hundreds of Kurds staged a violent protest Saturday in southeastern Turkey after police said two Kurdish rebels had been killed in a gun battle after a raid on their hideout.

The protestors demonstrated near where the two alleged members of the banned Kurdistan Workers' Party (PKK) died earlier in the center of Diyarbakir, the main city of the majority Kurdish region.

The rebel Free Syrian Army is suspending operations against regime forces during the mission of monitors deployed in Syria to implement an Arab League peace plan, its chief told Agence France Presse on Saturday.

"We have decided to stop all the operations, except those for self-defense," dissident Colonel Riyadh Asaad told AFP in a telephone interview from his base in Turkey.

Turkish Prime Minister Recep Tayyip Erdogan expressed regret Friday for the death of 35 Kurdish civilians in an air strike, saying it had been determined they were smugglers and not separatist rebels.

Speaking to journalists in Istanbul, Erdogan offered his condolences to the families of the victims for what he called an "unfortunate and distressing" incident.

The rebel Kurdistan Workers' Party (PKK) on Friday urged Kurds in Turkey to stage an "uprising" after an air force raid killed 35 villagers near the Iraq border.

"We urge the people of Kurdistan... to react after this massacre and seek a settling of accounts through uprisings," Bahoz Erdal from the armed wing of the PKK, labeled a terrorist organization by Ankara, said in a statement.
