AKCAKALE, Turkey (AP) — Turkey and Syria fired artillery and mortars across their volatile border for a fifth consecutive day on Sunday, in one of the most serious and prolonged flare-ups of violence along the frontier.
The exchange of fire stoked fears that Syria's civil war will escalate into a regional conflagration drawing in NATO member Turkey, once an ally of President Bashar Assad but now a key supporter of the rebels fighting to topple him.
Turkish Foreign Minister Ahmet Davutoglu had warned on Saturday that Ankara would respond forcefully to each errant Syrian shell that lands on Turkish soil.
Ankara's warning was coupled by an apparent diplomatic push by the Turkish leadership to promote Syrian Vice President Farouk al-Sharaa as a possible figure to head a transitional administration to end the conflict in the country.
In an interview with Turkish state television TRT Saturday, Davutoglu said that al-Sharaa was a figure "whose hands are not contaminated in blood" and therefore acceptable to Syrian opposition groups.
It was not clear whether the Turkish stance was coordinated with other allies, but the candid remarks by Davutoglu suggested some consensus might be emerging over a future role for him.
Al-Sharaa, 73, a close associate and longtime loyalist to the Assad family, has been a controversial figure since the start of the uprising.
He appeared in public in late August for the first time in weeks, ending repeated rumors that he had defected. The regime has suffered a string of prominent defections in recent months, though Assad's inner circle and military have largely kept their cohesive stance behind him.
Early on in the uprising, the Syrian president delegated to al-Sharaa, a skilled diplomat, responsibility for holding a dialogue with the opposition. A Sunni from the southern town of Daraa, birthplace of the Syrian uprising, al-Sharaa's silence since the start of the uprising made him a prime candidate for rumors that he broke with the regime.
"No one knows the system better than Farouk al-Sharaa," said Davutoglu, adding that al-Sharaa has not been involved in the violence and massacres in Syria.
The Syrian opposition is deeply fragmented, and various factions would likely disagree on whether they would accept him to lead a transitional government.
Meanwhile, there was little sign that the exchange of fire near the border, although still at a fairly low level, was ebbing. It began five days ago when a Syrian shell killed five civilians in a Turkish border town. Turkey's parliament subsequently approved a bill that would allow cross border military operations there.
Damascus offered a rare apology, but shells and mortar rounds continue to fly into Turkish territory.
On Sunday, an Associated Press journalist witnessed a round landing some 200 meters (yards) inside Turkey, near the border town of Akcakale. A short time later, eight artillery shells could be heard fired from Turkey.
In the Turkish town of Akcakale, mayor Abdulhakim Ayhan said shrapnel from the Syrian mortar round caused some damage to a grain depot, but no one was hurt. He confirmed that Turkish artillery immediately returned fire.
The Anadolu Agency reported that Assad's forces have been shelling the town of Tal Abyad, just across from Akcakale, which is controlled by Syrian rebels.
