Tensions between Iran and the US have escalated, with Iran taking two significant actions. 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 continued attacks in Lebanon. Iran had been engaged in interim agreement discussions with the US, but these recent developments may hinder progress.
