Rooftop protest: A man ignites a spray can in the centre of
Berne as the Swiss capital was locked down for the techno
parade.   Swiss police have arrested 61 people in clashes at a
politically-charged techno parade in Berne, which the
authorities say left 21 members of the security forces injured.
Trouble erupted in Berne's picturesque Old Town in the early
hours of Sunday during the unauthorised "Tanz Dich Frei" (Dance
Yourself Free) parade.  After a standoff between riot police and
dozens of masked and hooded "Black Bloc" hardliners, an AFP
reporter saw a group attempting to break down temporary barriers
protecting Parliament.  Police responded with tear gas and a
water cannon which sent the crowd scattering across the square,
as a helicopter circled overhead.  Some protesters held their
ground, pelting police and the water cannon with bottles,
fireworks and flares.  Police put the number of participants in
the parade at 10,000, and said the vast majority were peaceful.
Braving rain and unseasonably chill
