Popocatépetl volcano came to life on Sunday morning, sending a column of gas and ash 2,000 metres (6,500ft) into the sky in central Mexico. A 12km (7.5-mile) security ring around the volcano has been mandated, preventing passage close to the crater. Popocatépetl’s last major eruption was in 2000, when more than 40,000 people had to be evacuated.
