President Recep Tayyip Erdogan said Tuesday Türkiye was making "intense" diplomatic efforts to end the conflict roiling the Middle East, sparked by the Israeli-US strikes on Iran.
"Attacks on Iran, and missile and kamikaze drone attacks (by Iran) on neighboring countries in the Gulf have fueled instability," he said in a televised address.
"Through peace-oriented diplomacy, we are making intense efforts to resolve issues at the negotiating table," he added.
Earlier, Foreign Minister Hakan Fidan met Washington's Syria envoy Tom Barrack, ministry sources said.
He also spoke with his UK counterpart Yvette Cooper to discuss "the current security environment in the region", evaluating "in detail" the "diplomatic efforts that could be undertaken to end the hostilities and establish stability".
He also discussed regional developments with Qatar's Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani, with his Greek counterpart Giorgos Gerapetritis and with Nechirvan Barzani, president of Iraq's autonomous Kurdistan region. Fidan said Ankara was also in talks with Oman.
The United States and Israel launched strikes against Iran on Saturday. The war quickly widened with Tehran striking Gulf states that host US bases and Israel attacking Iranian-backed Hezbollah targets in Lebanon.
Türkiye, a NATO member and neighbor of Iran, had for weeks urged Washington and Tehran to reach an agreement during their rounds of negotiations over Iran's nuclear program and missile capabilities, warning that the region could not handle any more destabilization.
Fidan told members of Turkish media during a Ramadan fast-breaking dinner on Tuesday that Türkiye was "sensitively carrying out necessary initiatives with all our counterparts" to achieve peace in the region, and added it was critical to preserve the stability of Iran and the region.
"There isn't a single-layered negotiation, there is a multi-layered negotiation," Fidan said, according to a transcript of his comments shared on Tuesday.
"We have been talking to the Europeans for a few days... If you want peace, let's work together. We are urging them to take action. The Gulf nations are now facing a serious situation," he said.
"We are talking to the Omani (foreign minister). Oman is also still trying to do something there. We are talking to the Americans," he said.
Fidan warned against the conflict engulfing the whole region and affecting energy supplies. He added that the closure of the Hormuz Strait, where one-fifth of global oil trade skirts Iran's coast, could "push the United States to obtain a quick result".
He said Iran was trying to "create costs" for the US and its partners by attacking Gulf states and energy infrastructure, but added that he didn't believe Tehran could obtain the desired result that way.
"By bombing these places, Iran will say they should pressure the United States and end the war, but that doesn't seem like it will happen. I don't know how much Iran has left," he said, adding that Tehran could instead "bother" Israel with missile strikes.
