AUSTIN, Texas (AP) — Hundreds of Muslims are planning a rally at the Texas Capitol and to meet with lawmakers during the biennial Texas Muslim Capitol Day.

The rally Thursday is sponsored by the Council on American-Islamic Relations. Organizers say they expect a counter-demonstration. Council Executive Director Mustafaa Carroll said the event began in 2003 and has never drawn opposition before, but this year online threats have prompted the council to contact the FBI.

An FBI spokeswoman said she could not confirm or deny the threats.

Thursday's event comes a week after hundreds of protesters gathered outside a Muslim group's conference in the Dallas suburb of Garland and heckled participants.
