Tensions between Iran and the US have escalated, with Iran taking two significant actions on Saturday. The country has closed the Strait of Hormuz, a key waterway. Additionally, Iran's negotiators are heading to Switzerland for talks with the US, but it's expected that little progress will be made.

The actions are reportedly in response to Israel's ongoing attacks in Lebanon, which have angered Iran. The moves come as a blow to the interim agreement between Iran and the US. Further details on the situation are available from WXYZ Channel 7, which is continuing to monitor the developments.
