US secretary of state seeks to reassure UAE, Kuwait and Bahrain over security and US-Iran ceasefire deal

The US secretary of state, Marco Rubio, has said no country, including Iran, would be allowed to charge tolls for shipping in the strait of Hormuz as he sought to reassure US allies in the Gulf that Washington would take a firm line in peace negotiations with Tehran.

Rubio is to meet Gulf allies on Tuesday and Wednesday in an attempt to reassure them that the US remains committed to their security and the 60-day ceasefire deal struck with Iran last week will not embolden Tehran.
