The United States has warned its citizens about a possible increase in threats due to rising tensions with Iran.
In an advisory, the US Department of Homeland Security (DHS) said the ongoing conflict with Iran could lead to cyberattacks, violence, and extremist activity within the country.

The notice says that pro-Iranian hackers might try to attack US computer systems. It also said that hackers linked to the Iranian government could target US networks. Iran has also shown interest in targeting US government officials whom it blames for the 2020 killing of one of its top military commanders. The DHS also warned that the risk of violence from individuals acting alone could rise if Iranian leaders call for revenge attacks inside the United States.

US strike on Iran

The advisory came after the US carried out airstrikes on three major nuclear sites in Iran: Fordow, Natanz, and Isfahan, as part of a mission called Operation Midnight Hammer. The strikes involved over 125 aircraft, including seven B-2 Spirit bombers, which dropped more than a dozen 30,000-pound bunker-buster bombs on underground nuclear facilities. Tomahawk missiles were also fired at the Isfahan site.

The operation began at 6:40 p.m. ET, and all bombers exited Iranian airspace by 7:05 p.m. ET. According to General Dan Caine, Chairman of the Joint Chiefs of Staff, the aircraft flew from a base in Missouri, making it the longest B-2 bomber mission since 2001. The mission also involved refuelling and escorting aircraft, and a decoy group was sent in a different direction to maintain the element of surprise.
