Tens of thousands of Cubans are streaming past a memorial to the
late Venezuelan President Hugo Chavez in Havana.  It's a tribute
to the man who was the island's most important international
ally and a close friend of retired leader Fidel Castro.  People
formed a long, snaking single-file line at Revolution Square to
pay their respects to Chavez on Thursday, two days after he
succumbed to cancer.  Some saluted an oversize photo of Chavez
that was perched above a bed of white flowers and flanked by a
military honor guard. A few wept.  Around the city, flags flew
at half-staff.
