KUWAIT Iran’s foreign minister called on Sunday for a united front among Middle Eastern nations to fight militancy, in his first regional trip since Iran reached an agreement with world powers on the country’s nuclear program – an agreement that raised fears among its Gulf Arab neighbors.

“Any threat to one country is a threat to all … No country can solve regional problems without the help of others,” Mohammad Javad Zarif said at a news conference hosted by the Iranian embassy in Kuwait.

Zarif earlier met Emir Sheikh Sabah al-Ahmed al-Sabah and Kuwait’s foreign minister, Sheikh Sabah al-Khaled al-Sabah, who was not present at the news conference.

After Kuwait, Zarif traveled to Qatar, where he was to meet the Emir Sheikh Tamim bin Hamad al-Thani. He was due to go to Iraq next.

Most Gulf Arab states are worried that Iran’s July 14 accord will hasten detente between Tehran and Washington, emboldening Tehran to increase backing for Middle Eastern allies at odds with Gulf Arab countries.

“Iran stands behind the people in the region to fight against the threat of extremism, terrorism and sectarianism … Our message to the regional countries is that we should fight together against this shared challenge,” Zarif added.
