Venezuela walks out of Americas summit as teenage protester shot dead

Venezuela's foreign minister has walked out of a meeting of regional diplomats to discuss the South American country's political crisis, as a 17-year-old anti-government protester was killed during clashes with security forces.

The Organisation of American States meeting in the Mexican resort of Cancun again narrowly failed to approve a resolution that would have pushed back against some of Venezuelan President Nicolas Maduro's most radical actions.
