US Secretary of State John Kerry and Saudi Foreign Minister Adel al-Jubeir insisted Thursday that their countries' ties remain strong despite recent tensions over Washington's outreach to Iran.

The top envoys met in London for talks on a variety of Middle East issues, including the wars in Syria and Yemen and the imminent implementation of the Iran nuclear deal.

"We agree, first of all, the alliance, the friendship between the United States and the kingdom of Saudi Arabia remains a lynchpin of our efforts in the region. It's important. We both agree with that, on both sides," Kerry told reporters as he welcomed al-Jubeir.

Without mentioning Iran, Kerry expressed sympathy for Saudi Arabia's concerns -- shared by the United States -- over its web of influence in the Arab world.

"We also understand the challenges that the kingdom and other countries feel in the region about interference in their countries," he said.

"We want to try to see if there's a way, moving forward, to resolve some of these problems without moving to greater conflict. The last thing the region needs is more conflict," he continued.

"And I know the kingdom of Saudi Arabia agrees with that. But there are simple things they would like to see done that help prevent that."

Al-Jubeir responded: "I think if you look at the challenges our region faces, whether in Syria, whether in Yemen, whether terrorists, whether in 'Iran's interference in the affairs of the region', or Libya, the most effective ways for us to work though these challenges is through our close partnership and alliance with the United States of America."
