Students at Marjory Stoneman Douglas High School in Parkland, Florida, are returning to class Wednesday morning for the first time since the deadly shooting two weeks ago.

According to ABC News, there will be extra security and all off-duty Broward County Law Enforcement Officials will be there to greet the students.

Grief counselors are on campus “to provide a lot of love, a lot of understanding,” Broward Schools Superintendent Robert Runcie said, and counselors will be on campus indefinitely.

The school’s principal also noted that today will not be about learning, tweeting at students to “come ready to start the healing process and reclaim the nest.”

“I don’t think anyone is physically prepared or mentally prepared to walk through those red gates,” Student Nicole Velasquez said.

Officials say the freshman building where the shooting happened will remain closed. Students have taken to Twitter, offering support and reminders to each other with the hashtag “ReclaimTheNest.”

Meanwhile, Dick’s Sporting Goods has announced it will stop selling assault-style rifles in its stores.

And Dick’s Chairman and CEO Edward Stack says the store won’t sell guns to anyone under 21 years old.

The gunman in the Parkland school shooting had used an AR-15 rifle.
