WASHINGTON (AP) — President Donald Trump spoke for more than an hour Tuesday by phone with Russian President Vladimir Putin.

Syria, Iran, North Korea and Ukraine were on the agenda, the White House said.

Trump called it a "great call" Tuesday afternoon as he left the White House to spend Thanksgiving in Florida. Noting the length, he said he and Putin spoke "very strongly about bringing peace to Syria" and "very strongly about North Korea."

Trump's phone call with the Russian president came a day after Putin met with Syrian President Bashar Assad. Putin hosted Assad at a Black Sea resort ahead of a summit later this week with Russia, Turkey and Iran. Assad was called to Russia to get him to agree to potential peace initiatives drafted by the other three countries, the Kremlin said.

The Kremlin said Putin briefed Trump in the phone call about his talks with Assad and plans for a political settlement in Syria. Putin also called for coordination of anti-terror efforts with the U.S. Afghanistan was also discussed.

Trump and Putin spoke informally several times earlier this month when they attended a summit in Vietnam. They agreed on a number of principles for the future of war-torn Syria.
