The US Department of Homeland Security on Sunday issued an advisory regarding a heightened threat environment across the United States due to the direct involvement of the country in the ongoing conflict between the nations of Israel and Iran.

The department said there are currently no specific credible threats against the homeland.

“It is our duty to keep the nation safe and informed, especially during times of conflict,” said Secretary Kristi Noem.

“The ongoing Israel-Iran conflict brings the possibility of increased threat to the homeland in the form of possible cyberattacks, acts of violence, and antisemitic hate crimes," Noem said.

Tension Escalates Further In Middle East

US President Donald Trump on Saturday announced bombing Iran's three nuclear sites and said that with this operation, there would either be peace or more tragedy for Tehran.

The sites are Fordow, Natanz, and Esfahan.

He thanked Israeli Prime Minister Benjamin Netanyahu as well as the Israeli army and said it was teamwork.

In an address to the world and nation from the White House, President Trump said: "A short time ago, the US military carried out massive precision strikes on the three key nuclear facilities in the Iranian regime. Fordow, Natanz, and Esfahan. Everybody heard those names for years as they built this horribly destructive enterprise. Our objective was the destruction of Iran's nuclear enrichment capacity and a stop to the nuclear threat posed by the world's number one state sponsor of terror.

"Tonight, I can report to the world that the strikes were a spectacular military success. Iran's key nuclear enrichment facilities have been completely and totally obliterated. Iran, the bully of the Middle East, must now make peace. If they do not, future attacks will be far greater and a lot easier.

Iran-Israel Conflict

The conflict started a week ago when Israel launched airstrikes against Iranian nuclear and military sites, primarily targeting uranium enrichment facilities to prevent Iran from developing nuclear weapons.
