WASHINGTON (Sputnik) — The US top diplomat spoke in the wake of reports that Iran had dispatched two naval ships, including a destroyer, to waters off Yemen earlier in the day.
"Iran needs to recognize that the United States is not going to stand by while the region is destabilized or while people engage in overt warfare across lines — international boundaries — in other countries," Kerry told the PBS television.
The US State Secretary added that the United States were able "to stand up to interference that is inappropriate or against international law."
Earlier, Yemeni officials had claimed that Iran was supplying weapons to the Shiite Houthi rebels, who control large parts of Yemen including capital Sanaa.
Tehran has criticized the Saudi-led air operation targeting the Houthi positions in Yemen and has called for a ceasefire in the country.
