LONDON, Nov 11 (Reuters) - A large number of schools in Northern Ireland have been sent a threatening email, the Northern Ireland Education Authority said on Wednesday, but they have been advised to stay open as the authority said police did not regard it as a credible threat.
"The message has similarities with a bogus threat sent last month, which was declared a hoax by PSNI (police)," the Education Authority said.
