Elizabeth met with 15-year-old Millie Robson, who wore an Ariana Grande T-shirt while smiling in bed. Evie Mills, 14, was joined by her parents when she met the Queen.
And Elizabeth also met with 12-year-old Amy Barlow, who was surrounded by balloons and a teddy bear.
Earlier in the week, Elizabeth released a statement in response to the attacks.
“The whole nation has been shocked by the death and injury in Manchester last night of so many people, adults and children, who had just been enjoying a concert,” she said in the statement. “I know I speak for everyone in expressing my deepest sympathy to all who have been affected by this dreadful event and especially to the families and friends of those who have died or were injured.”
“Hundreds of friends, parents, children, and partners are confronting unimaginable grief today, and we send our thoughts to them all,” the father of two said. “We also send our thanks to the people of Manchester for their display of strength, decency, and community that is an example to the world."
