"The Texas Department of Public Safety said the man had demanded to see his 'sister,' who may not actually be related to him and who is currently in U.S. federal custody..."

"... for 'terroristic events' in Afghanistan. 'The man claims he and his sister will be going to Jannah (Muslim belief of heaven) after he sees her,' the department said in a statement earlier on Saturday. The congregation had been holding a service... being live streamed on its Facebook page when... a man could be heard shouting about dying and not liking police officers... Many Jews expressed exhaustion on Saturday at the security concerns surrounding practicing their faith at a time when antisemitism comes from many sources, including white supremacists and Islamic extremists.... 'This is Jewish life in 2022... If you attend religious services without armed guards at the entrance and without fear of attack... you do not experience religious life as American Jews do.'"
