US President Trump said he may negotiate with Iran.

Iran's Islamic Revolutionary Guard Corps said in a statement early on Sept. 9 local time that its Aerospace Force used ballistic missiles to strike the US destroyers USS Delbert D. Black (DDG-119) and USS John Paul Jones (DDG-53), which it said were equipped with cruise missiles and the Aegis system. The IRGC said the strikes caused severe damage, framed them as retaliation for US attacks and harassment of Iranian tankers and vessels, and warned against miscalculation.

Anthropic said the four incidents all occurred during cybersecurity assessments built by the same evaluation partner.
