Hong Kong protesters turn university campuses into fortresses

Protesters and students have been barricading themselves inside Hong Kong's universities.

They built concrete walls and watchtowers and had weapons that included bows and arrows, catapults and hundreds of petrol bombs.

The idea is to stop police from raiding the facilities.

It is the latest development in anti-government protests in the city-state, which are now into their sixth month.
