President Recep Tayyip Erdoğan said Friday that he hopes that Turkey and the U.S. will open a new page under the Trump administration as bilateral ties gain momentum since the election of the U.S. president.

Speaking at the the Atlantic Council Energy Summit, Erdoğan said Turkey and the U.S. have succedded great strategic improvements with high-level cooperation before, and said the current regional crises have created a need for even stronger cooperation between the allies.

Erdoğan told that the conference that the U.S. support for the PKK-affiliated People's Protection Unit (YPG) inside Syria and delaying the extradition of the Gülenist Terrorist Group (FETÖ) leader, Fetullah Gülen damage solidarity between Washington and Ankara but Trump's attitude towards those issues could open a new era.

He also said that the Trump administration gives signals that it is more determined in war on terror than the previous one.

He said Turkey's southern border region with Syria had come under serious mortar fire over the last two days by YPG terrorists and Turkish forces were retaliating as necessary.

"YPG forces were still present in a region of northern Syria west of the Euphrates river and must be pushed back from the area."

He warned that focusing military efforts in Syria against Daesh alone would strengthen the other terrorist groups such as YPG.

Erdoğan said the reputation of the UN Security Council and the EU is being sacrificed for the sake of a few countries and criticized the international community for failing to respond to atrocities committed by the Assad regime, saying the war crimes would not have taken place if the international community and the United Nations Security Council had taken a strong stance.
