A 'huge explosion' has been reported on the Paris metro leading to dozens of passengers being evacuated from a station. The incident, on Line 6 in or near to the the Place d'Italie subway stop, appears to have been caused by an electrical fire, but has raised fresh terror fears as France remains on high alert. As many as eight passengers are believed to have been injured in the explosion, either in the apparent blast or from smoke inhalation. It is unclear at this time what caused the incident, but security personnel are believed have sealed off the area. Dozens of armed police are at the scene around the Place d'Italie as the situation is investigated. Early reports suggest the explosion was caused by an electrical fire and that eight people have been injured. France remains on a high state of alert after last Friday's suspect terror attack at the Louvre in Paris in which soldiers shot an Egyptian man wielding a machete. Abdullah Reda al-Hamamy was shot several times after he allegedly attacked soldiers outside the museum - home to the Mona Lisa and other famous works of art - with a machete and cried "Allahu Akbar" The soldiers can been seen in footage of the incident standing anxiously above him pointing their guns following the attack. The victim is now being treated for serious injuries in hospital after soldiers fired five shots during the suspected terror attack. Soldiers patrolling as part of France's on-going State of Emergency stopped the attacker getting into the building. The country has suffered a number of horrifying terror attacks over the past two years, including the Charlie Hebdo murders in Paris and the Nice lorry massacre. President Francois Hollande had declared a state of emergency in France and war on terrorism after the attacks shook the country to its core. The country has been living in fear of a fresh attack by jihadis, but tonight's explosion is not currently thought to be terror-related.
