CELTIC-mad rocker Sir Rod Stewart has thrown his support behind US students who are walking out of schools against gun violence.

The Maggie May hitmaker - who is a regular face at Parkhead - shared a message of solidarity on Twitter on Wednesday.

He wrote: “To the students participating in today’s walkouts and demanding their safety, your courage is seen all over the world. Stay strong, we’re with you. #NationalStudentWalkout -Rod xxx.”

The 73-year-old’s message went down a storm with his fans who rushed to commend him for his support.

The walkouts have also drawn support from companies such as media conglomerate Viacom, which paused programming on MTV, BET, Nickelodeon and its other networks for 17 minutes.

Sir Rod’s comments came as students across America left their classrooms on Wednesday to urge gun control and safety measures following a spate of massacres.

Bowing their heads in honour of the dead and carrying signs with messages like ‘Never Again’ and ‘Am I Next?’, they denounced the National Rifle Association (NRA) and the politicians who support it.

“Enough is enough” was the rally cry in a wave of protests one historian called “the largest of its kind in American history.”

The demonstrations extended from Maine to Hawaii as students joined the youth-led surge of activism set off by the February 14 massacre at Marjory Stoneman Douglas High School in Parkland, Florida.

Students left class at 10am local time for at least 17 minutes, one minute for each of the dead in the Florida shooting.

Some led marches or rallied on American football fields, while others gathered in school gyms or knelt in the hallway.

At some schools, hundreds of students poured out. At others, just one or two walked out in defiance of administrators.

They lamented that too many young people have died and that they’re tired of going to school afraid they will be killed.

But whether the students can make a difference on Capitol Hill remains to be seen.

Congress has shown little inclination to defy the powerful NRA and tighten gun laws, and Trump backed away from his initial support for raising the minimum age for buying an assault rifle to 21.

Wednesday’s coordinated protests were organized by Empower, the youth wing of the Women’s March, which brought thousands to Washington last year.
