WASHINGTON (Reuters) - US President George W. Bush's national security adviser, Turkey's Foreign Minister Recep Tayyip Erdoğan, left Turkey yesterday for talks with the United States, Its military bases in Syria. In the meantime, dozens of fighters were killed in bloody counter-attacks launched by an advocacy organization against the forces of Qusd in eastern Syria, according to the Syrian Observatory for Human Rights.

In detail, Bolton's departure for Ankara came without meeting Erdogan, after failing to secure guarantees from Ankara, not to attack Syrian democratic forces in the event of a US withdrawal from Syria.

Turkey has denied Erdogan has pledged to his US counterpart, Donald Trump, to "protect" Kurdish militants in Syria, US Secretary of State Mike Pompeo said.

"With regard to Pompeo's statements, it is absolutely inconceivable that such a guarantee was given during talks (between Erdogan and Trump) or through other channels," said Turkish presidential spokesman Ibrahim Kalin.

Bolton said that "there must be conditions, including ensuring the safety of Kurdish allies, before the withdrawal of US troops from Syria."

In a speech in Ankara yesterday, Erdogan said Bolton's remarks "are unacceptable to us and can not be tolerated" after a meeting in Ankara between Bolton and Ibrahim Kalin.

"John Bolton made a big mistake," he said.

"While these people are terrorists, some say they do not approach them, they are Kurds ... They may also be Turks, Turkmans or Arabs," Erdogan said. If they are terrorists, we will be needed, no matter where they come from. "

He also said: "We will move soon to act, to eliminate terrorist groups in Syria."

In the context, Turkey announced on Tuesday that it expects the United States to recover the weapons it handed over to Kurdish fighters in Syria, to fight militants.

"What we expect is to recover all the weapons that have been delivered," Calin told a news conference after his meeting with Bolton.

"They told us they were working on that, but the details will be clearer in the coming days," Kalin said, adding that Turkey had no "acceptable alternative" to recovering these weapons.

Turkish newspaper Hurriyet said Turkey was expected to ask US officials to either hand over or destroy US military bases in Syria, a request that could further complicate discussions about the US withdrawal from there.

The newspaper carried the title "handed over or destroyed," in reference to what she said, it is 22 US military bases in Syria. The paper quoted unspecified sources as saying that Turkey would not accept that Washington hand over these bases to the units protecting the Kurdish people.

On the other hand, the Syrian Observatory for Human Rights that the counter-attacks, launched by the organization Daadish, on Sunday evening, taking advantage of a sandstorm and bad weather, killing 23 fighters of the Syrian Democratic Forces.

The organization had announced that a suicide bomber from his followers had killed several people at a military base in the Syrian city of Raqqa, controlled by Kurdish groups backed by the United States.

The Syrian-led Kurdish Democratic Forces said a gunman blew himself up, killing a civilian and wounding several of its fighters.
