Turkish president visits Iran despite tensions with Tehran over Yemen's crisis

Turkish President Recep Tayyip Erdogan is visiting Iran despite tensions with Tehran over the crisis in Yemen, where airstrikes by a Saudi-led coalition are targeting Iran-backed Shiite rebels who have taken over much of the country.

The Saudi campaign has turned Yemen into a new front in the conflict between the kingdom and Iran.

Iran's state TV says Erdogan arrived in Tehran on Tuesday, accompanied by several government ministers.

Erdogan has backed the Saudi-led campaign against the Houthis in Yemen. Last month, he lashed out at Iran, accusing it of trying to "dominate the region" and of testing the limits of the region's tolerance.

Iran denies it is helping the Houthis militarily. Tehran also sees NATO missiles in Turkey and Ankara's relations with Israel as potential threats.
