The U.S. naval commander charged with securing the waters around the Arabian Peninsula says Iran’s landmark nuclear deal with world powers has done little to stop the Islamic Republic from pursuing other activities the U.S. considers destabilizing.

Vice Adm. Kevin Donegan made the comments in an interview with The Associated Press on Sunday at the start of the Dubai Airshow.

The commander of the U.S. Navy’s 5th Fleet said he did not want to underplay the significance of Tehran’s willingness to come to the negotiating table, but says other actions such as smuggling military equipment to Yemen and harassing ships transiting the Gulf continue just as they did before the July deal.

Donegan assumed command of the U.S. Navy’s Bahrain-based 5th Fleet in September.
