Pakistan have reportedly used fighter jets and intelligence to thwart an alleged plan by Israel to shoot down the jet carrying Iran's highly-qualified negotiators attending talks with Donald Trump's relatives and golf buddies.
Israel's plans to kill Iran's top surviving team in order to thwart talks were already known, but supposedly shelved under pressure from the US. However, Pakistani intelligence believed that Israel would attempt to shoot down the negotiators' plane either en route to, or returning from, the talks in Pakistan.
The Pakistan air force used recently-supplied Chinese J-10C fighters for the escort mission. This led to claims that China's air force also participated in the escort, but this does not appear to have been the case.
