Regional leaders in Bolivia have called for a general strike in six of the country's provinces in the latest protests against President Evo Morales's plans to reform the constitution.

The six opposition-run provinces contribute a large percentage of Bolivia's national income.

Organizers of the strike say it is aimed at denouncing the framework for a new constitution approved by leftist allies of Mr. Morales on Saturday.

President Morales says the constitutional changes will give Bolivia's indigenous majority more political power. Critics say the changes unfairly reduce the power of Bolivia's nine provinces.

Under the new constitution, Mr. Morales would be allowed to seek re-election as many times as he likes.

The president's allies hold a majority in the constitutional assembly that approved the framework for the new constitution. Most opposition delegates boycotted the vote.
