Muslims in San Antonio are responding to posts on President Donald Trump's Twitter page after he retweeted anti-immigrant videos.
Sakib Shaikh, spokesman for the Muslim Children Education and Civic Center, said many in the community don't feel safe.
"[Trump] says outlandish things on Twitter but this was beyond the pale," Shaikh said. "It's probably the worst thing he's done on social media."
One video claims to show Muslim extremists throwing a boy off a roof. Another captioned as a Muslim migrant beating up a Dutch boy is believed to be fake.
"We don't know who they are," Shaikh said. "They are just random videos. We don't know when they took place, we don't know the names of the people in the videos, we don't know their motivation."
The retweets were originally posted by an extreme right fringe party in Britain. Prime Minister Teresa May called the posts “wrong.”
"It's immoral," Shaikh said. "Sharing these videos crosses the line and it could put people’s lives in danger. We tell the community to take extra precaution, to travel in groups, and we advise people not to stay too late at the mosque."
Shaikh added that President Trump should visit a mosque and learn about what the religion is all about.
"Muslims have been around for a long time," he said. "Our religion really isn't that foreign.”
