Hillary Clinton said Monday that the weekend bombings in New York and New Jersey show the U.S. faces a real threat from terrrorism, and argued that she's the only candidate qualified to address that threat.

"This threat is real, but so is our resolve. Americans will not cower. We will prevail. We will defend our country and we will defeat the evil, twisted ideology of the terrorists," she told reporters Monday morning.

"I'm the only candidate in this race who has been part of the hard decisions to take terrorists off the battlefield," she added. "I've laid out a comprehensive plan to meet the evolving nature of this threat and take the fight to [the Islamic State] everywhere they threaten us, including online."

"Let us be vigilant. Be not afraid," Clinton said. "If you see something or hear something, report it immediately."

Clinton's remarks come shortly after a series of reportedly coordinated bombings rocked parts of New York and New Jersey. Her comments also follow on a reportedly Islamic State-inspired stabbing attack in Minnesota this weekend.

The FBI released a statement Monday morning asking people to be on the lookout for Ahmad Khan Rahami, a New Jersey man thought to be connected to attacks this weekend.
