Texas Denton County Sheriff Tracy Murphree: urged Americans to "pay attention" to the Islamic jihadists who "want to kill you".

His comments came after a suicide bomber killed 22 people and injured 64 at an Ariana Grande concert in the UK.

His remarks quickly drew both praise and outrage online.

"I stand behind it," Mr Murphree told a local NBC news affiliate on Tuesday. "We need to be realistic about the world we live in."

Mr Murphree wrote on Monday after the attack: "This is what happens when you disarm your citizens. When you open your borders without the proper vetting.

"When you allow political correctness to dictate how you respond to an enemy that wants to kill you.

"The left tells us we must submit and accept these radical beliefs and bend over backwards to make sure we don't hurt anybody's feelings."

"The left wants to cater to the very group that would kill every group they claim to support. Folks this is an enemy hell bent on killing you," he continued.

He later wrote: "You better wake up America. While you are distracted by the media and the crying of the left, Islamic Jihadist are among us and want to kill you."
