LONDON (Reuters) - At least 10 people are believed to have died after a reported blast at a concert venue in the northern English city of Manchester, which police are treating as a possible terrorist incident, the BBC reported on Tuesday.
"Senior national counter-terrorism officers are assembling in London. Early estimates put fatalities at Manchester Arena in double figures," a BBC reporter said on Twitter.
The BBC and Sky News reported shortly before that local police were treating the blast as a possible terrorist incident.
