LONDON: Eight schools across the United Kingdon today received bomb attack threats, including one attended by Pakistani teenage activist and Nobel Laureate Malala Yousafzai, prompting authorities to launch a probe.

The schools in England and Scotland - six in Birmingham alone and two in Glasgow - received the threats this morning following which the buildings were evacuated, Times of India reported.

Edgbaston High School for Girls in Birmingham, where 18-year-old Malala is enrolled, received a call just after 0800 GMT making a bomb threat. West Midlands Police was still investigating the call but pupils were allowed back into their classes after brief evacuation as the call is believed to be a hoax. 

The other schools in the city to be hit by hoax calls included Shireland Collegiate Academy, Bristnall Hall Academy, Perryfields High School, Hall Green Secondary School and Oldbury Academy.

Tuesday’s calls follow similar calls last week which were also deemed as a hoax.

"This morning we have reports of a further six bomb threats, following similar threats made to several schools last week. At this stage there is nothing to suggest there is any credible threat to any of the schools," Detective Inspector Colin Mattison of West Midlands Police said in a statement.

"Our response officers have been sent to the locations to ensure there is no threat to anyone's safety and support the schools. A police investigation is ongoing to find the person responsible for these calls," he said.

Two schools in Glasgow also received bomb threats this morning and police officers investigating them also said "nothing untoward" was found following an investigation.

A spokesperson for Police Scotland said: "Two schools in Glasgow have received a threat via the telephone. Staff and police have searched both school buildings and nothing untoward was found.

"Schools are operating as normal and officers are continuing inquiries. At this stage, police are treating these incidents as malicious calls."
