EL PASO, TEXAS (NYTIMES) - A supporter of President Donald Trump attacked a BBC camera operator during a presidential rally in El Paso, Texas, on Monday night, the broadcaster said.

"BBC cameraman Ron Skeans was violently pushed and shoved by a member of the crowd while covering a President Trump rally in Texas last night," a BBC spokesman said in an e-mail on Tuesday (Feb 12).

Mr Trump was in El Paso to increase support for his proposed wall on the United States border with Mexico, in his most significant rally since his funding demands for the project temporarily shut down the government.

The President was talking about a decline in attacks on African, Hispanic and Asian-Americans when the cameraman was pushed.

A 36-second clip from Mr Skeans' camera before, during and after the shove was widely circulated on social media on Tuesday.

It shows a protester in a red Make America Great Again cap, who has not been publicly identified, shouting at members of the media as he is restrained by someone who appears to be part of the event's security team.

As the man struggles, the crowd's chant shifts from "USA" to "Let him go".

Mr Gary O'Donoghue, the BBC Washington correspondent who covered the El Paso rally on Monday, said the supporter had "tried to smash" the camera before security escorted him out of the venue.

The BBC condemned the attack.

"It is clearly unacceptable for any of our staff to be attacked for doing their job," the statement on Tuesday said.

The President could see what was happening and checked "that all was OK", the statement added.

The White House Correspondents' Association also condemned the crowd member's actions, saying in a statement that "the President of the United States should make absolutely clear to his supporters that violence against reporters is unacceptable".

Since the beginning of his presidency, Mr Trump has had a strained relationship with the news media. He has repeatedly called journalists "the enemy of the people", and used the term "Fake News" on Twitter at least 174 times last year alone.

In August, experts from the United Nations and a human rights body condemned the President's attacks on the news media and warned that they could incite violence against journalists.

"His attacks are strategic, designed to undermine confidence in reporting and raise doubts about verifiable facts," Mr David Kaye, the UN special rapporteur on freedom of expression, and Mr Edison Lanza, who holds the same position at the Inter-American Commission on Human Rights, said in a statement.

"We are especially concerned that these attacks increase the risk of journalists being targeted with violence," they said.

During an interview last month, the publisher of The New York Times, Mr A. G. Sulzberger, asked Mr Trump about "potentially dangerous" rhetoric against journalists.

In his response, Mr Trump took credit for popularising the term "fake news" but said he was not responsible for how it was used by other governments.

Mr Skeans told the BBC that he "didn't know what was going on" when he was violently shoved on Monday, but that he was now fine.
