Homeland Security chief warns: You’d ‘never leave the house’ if you knew what I know about terror

Homeland Security Secretary John Kelly has a fierce warning: The terror threat is bigger than most people know.

"It can happen almost here any time. I was telling Steve on the way in here, if he knew what I know about terrorism, he would never leave the house" he said during an appearance on Fox & Friends on Friday.

Kelly pointed to the four terror attacks across the globe that have occurred in just the last week, in the the Philippines, Egypt, Indonesia and England.

All four are linked to the terror groups as well, he said.

"it's everywhere," he said of the threat of terror. "It's constant. It's nonstop. The good news for us in America is we have amazing people protecting us every day. But it can happen here almost anytime."

His comments came as Egyptian President, Fattah al-Sisi, called a meeting of security officials after masked men attacked buses and a truck filled with Coptic Christians in Minya.

Ten people have been arrested in connection to the bombing in Manchester at an Ariana Grande concert that killed 22 people and injured more than 100 others.

Indonesian police have arrested at least three people suspected of being linked to suicide bombings in Jakarta that were carried out on Wednesday. ISIS claimed responsibility for that attack as well.
