Protesters rally in Madrid hours ahead of Pope's visit

Thousands of protesters have rallied in the Spanish capital, Madrid, against the cost of a visit by the Pope, hours before he is due to arrive.

A number of the demonstrators clashed with police after marching to the central Sol square chanting slogans.

Earlier, Spanish police arrested a Mexican student for allegedly plotting to gas the anti-Pope rallies.

The trip comes at a time of economic hardship in Spain, although organisers say the pilgrimage is self-funded.
