John Bolton warned on Sunday that the Trump administration would send a “clear and unmistakable message” to Iran as a carrier strike group was traveling to the region amid tensions in Gaza.

President Trump’s National Security Advisor said in a statement that the country was deploying USS Abraham Lincoln Carrier Strike Group and a bomber task force to the region.

“The United States is not seeking war with the Iranian regime, but we are fully prepared to respond to any attack, whether by proxy, the Islamic Revolutionary Guard Corps, or regular Iranian forces,” Bolton said in the statement.

The Navy said last month that the strike group left Norfolk, Virginia on April 1 on a regularly scheduled deployment.

The bellicose language from Bolton comes as Gaza militants fired hundreds of rockets into southern Israel on Sunday, killing at least four Israelis.
