White supremacists on social media and Donald Trump supporters wrote about an upcoming race war in the wake of Thursday night's murders of five Dallas police officers.

In a tweet picked up by Vocativ, Twitter user Celtic Phoenix wrote: '3 Police officers shot dead and 10 wounded in Dallas today. Things are heating up, hope you're all prepared.'

He later shared a video of protesters, writing: 'How many of these people do you think have jobs? The solution might be as simple as cutting off welfare.

Another Twitter user, WASP, wrote of the shooting: 'Yep, I'm sick of this. We DEMAND WHITE ONLY areas, schools, shopping...u hear that #FoxNews #Dallas FK BLM, about to join #KKK.'

Meanwhile, after Trump wrote a Facebook message paying tribute to not only the murdered officers in Dallas but also the deaths of Philando Castile and Alton Steling, some of his followers made comments about the Dallas shooting being an attack on white Americans.

Tense times: White supremacists have begun to write about a 'race war' on social media in the wake of Thursday's fatal shooting of five police officers (police officer on the scene in Dallas on Thursday above)

Comments: One woman claimed that he best friend's father-in-law was one of those killed in a comment on Trump's page She then wrote: 'The people whom he was protecting, turned on him and killed him. That's what us whites get for trying to help!!'

'Last night’s horrific execution-style shootings of 12 Dallas law enforcement officers – five of whom were killed and seven wounded- is an attack on our country. It is a coordinated, premeditated assault on the men and women who keep us safe,' wrote Trump on Friday morning.

'We must restore law and order. We must restore the confidence of our people to be safe and secure in their homes and on the street.

'The senseless, tragic deaths of two people in Louisiana and Minnesota reminds us how much more needs to be done.'

Some of the comments that followed showed images of black men being lynched, while others wrote about the war on white Americans.

'I lay the blame for this directly at Obamas 2 feet, he has done everything to divide this country. We have a war on the police,We have a war on Christianity, We have a war on white Americans. All since he came into office! We have to take our country back,' wrote one woman.

Another wrote, in a lengthy comment: 'My best friends Father-in-law was 1 of the 5 killed. He was a good man who loved his family. He took an oath to protect and serve. Meanwhile, the people whom he was protecting, turned on him and killed him. That's what us whites get for trying to help!!

'We get shot and killed. We NEED you Trump!! We need you now. We can no longer wait for November...Obama is trying his hardest to tear this country apart before you come into office.

'He wants a full on race war. And sooner or later, these pissed off white Americans are going to give them exactly what they ask for. It's time to take a stand and fight for our lives and for our heritage!!!

'It's time to end #WhiteGenocide and #WhiteHatred it's time our people stop being gunned down in the streets and attacked by groups of blacks.

'I urge every white American to get their concealed carry license. I urge you to protect yourselves and your family. If things keep going the way they're going, our law enforcement will quit. They're tired of sticking their necks out for people who only want bloodshed.

'Soon were not going to have anyone we can call when someone breaks in to hurt your family. You're gonna have to take it upon yourself to protect you and yours. Get ready America!!!'

That same woman claimed that her best friend's father in law was one of the five offices killed in Dallas.

She later commented on her own comment, writing: 'I'm thinking of starting a Facebook page. I feel like I need to do something. But I don't know how well that would work.

'It's sad that so many people in this nation are brainwashed into feeling ashamed and sorry for being white. We need to have Pride in ourselves. They have their black pride. Why can't we?'

Comments: 'We have limited time to organize and prepare. The plug is being pulled on us,' wrote another Trump supporter on his Facebook page

Thoughts: '3 Police officers shot dead and 10 wounded in Dallas today. Things are heating up, hope you're all prepared,' wrote one man on Twitter

In response to that original comment another woman wrote: 'Why 13% of the most ignorant, non-productive trash are running this country. The only power they have is the power idiots like you have given them. And what have they done with it?

'I'd relish the day when Whites stand up to take the country back. I'll be right there with them and I hope one of you bleeding heart liberals don't get in my way.'

The most popular comment, liked over 26,000 times on Trump's Facebook page, said: 'STARTING Race Wars is only PART of what brings this nation to "MARTIAL Law" - and "THE MOMENT" Martial Law is enacted, Obama EXTENDS his presidential role. WAKE UP - He's NOT a savior or friend to Americans of ANY color, he and Clinton are your worst enemies!'

And another man wrote on Trump's page in a comment liked over 300 times: 'We have limited time to organize and prepare. The plug is being pulled on us, this is not "happenchance", this is a coordinated effort by enemies of our way of life. We are at war, and it is on our soil.

'Anyone interested in planning together, please message me and I will set up a virtual and physical classroom (for those close to me) provide help with planning and organizing. I will assist with communications, emergency preparedness, Intelligence gathering and distribution, training and support.

'It is time. In defense of the Constitution of our United States of America, and a way of life deserving of protection by free men.'

Former congressman Joe Walsh also blamed the deadly sniper attack on President Obama, writing: 'Obama says Cops are racist so 2 uneducated black thugs shoot 10 Dallas cops tonight.'

He then wrote: '3 Dallas cops killed, 7 wounded. This is now war. Watch out Obama. Watch out black lives matter punks. Real America is coming after you.'
