Friends at the ANU have told me that the entire campus is being evacuated following a large explosion in the Research School of Chemistry. No casuaties reported as yet and the campus evac would seem to be precautionary as opposed to there being a threat of any sort.
Should be hitting the local news soon I would expect.
UPDATED: Thanks to TAD for the link, the ABC have the story up here. Mighty big boom by the sound of it.
FURTHER UPDATE: The Canberra Times has coverage here.
ANU security declared the campus closed soon afterwards and sent all students and staff home for the afternoon.
Friday afternoon at ANU? All two of them then?
