The US says Turkey agrees to a ceasefire in Syria

President Trump, speaking this afternoon from the tarmac at Naval Air Station Joint Reserve Base in Forth Worth, called the US-announced ceasefire in Turkey an “incredible outcome” that saved lives.

“When those guns start shooting, they tend to do things, but I will tell you, on behalf of the United States I want to thank Turkey, I want to thank all of the people that have gotten together and made this happen,” Trump said. “I want to thank everybody. And the other thing I want to thank as a group, I want to thank the Kurds, because they were incredibly happy with this solution. This is a solution that really — well it saved their lives, frankly. It saved their lives.”

However, Turkish foreign minister said this is “not a ceasefire” but said they will “pause the operation” in Syria.

About the terms of the ceasefire: As part of that agreement, the US convinced the Syrian Kurds/SDF to dismantle their defensive fortifications and pull troops from the border to appease Turkey.

The US also conducted joint patrols and shared intelligence with the Turkish military as part of that arrangement.

The Kurds complied with the request to pull back and dismantle their fortifications. Turkey opted to invade despite those efforts. Source
