DUBAI, United Arab Emirates — One person was killed and seven others were wounded on Sunday in an attack by Iranian-allied Yemeni rebels on a Saudi airport, Saudi Arabia said. The strike came as the American secretary of state, Mike Pompeo, traveled to the country for talks on Iran.

Regional tensions have flared in recent days. The United States abruptly called off a military strike against Iran last week in response to the shooting down of an unmanned American surveillance drone.

The Trump administration has vowed to combine a “maximum pressure” campaign of economic sanctions with a buildup of American forces in the region. A new set of sanctions on Iran is expected to be announced on Monday.

Sunday’s attack by the Yemeni rebels, known as Houthis, targeted the Saudi airport in Abha. Saudi Arabia has been at war with the Houthis in Yemen for more than four years.
