Following the terrorist attack outside her concert on Monday night, Ariana Grande has canceled several of her upcoming shows.

The singer has canceled seven concerts on her Dangerous Woman tour between now and June 5. The next show was slated for tomorrow, May 25 in London. A second London show was scheduled for Friday. The other canceled dates: Sunday, May 28 in Antwerp, Belgium; Wednesday, May 31 and Thursday, June 1 in Lodz, Poland; Saturday, June 3 in Frankfurt, Germany; and Monday, June 5 in Zurich, Switzerland.

If Grande doesn’t cancel any more concerts, her next show will be held Wednesday, June 7 in Paris.

Several events in England have been canceled as the country heeds a “critical” terror warning, the highest possible. The government is warning that another attack could be imminent. Wonder Woman’s London premiere was canceled this week, as were upcoming shows from Blondie and Take That.
