Ariana Grande has expressed her sorrow after an explosion killed 19 people at the end of her concert in Manchester.
The US star is thought to be physically unhurt, but has posted a tweet saying: “Broken. from the bottom of my heart, i am so so sorry. i don’t have words.”
The blast happened just after the 23-year-old singer had finished performing at Manchester Arena on Monday evening.
Her manager Scooter Braun has also posted a statement, saying “our hearts are broken”.
The arena was packed with thousands of her fans at the time – including a large number of teenage girls, who make up most of her fan base.
