Volcanic eruption halts all UK flights

A Volcano has erupted in Iceland, and has led to all flights in and out of the UK being cancelled until 18.00 GMT. The eruption has led to an enormous amount of ash entering into the atmosphere that can be potentially hazardous to aircrafts. Experts have warned that tiny particles of rock, glass and sand contained in Volcanic ash can be hazardous to aircrafts.
