Venezuela lifted a nationwide curfew but kept martial law in effect in the wake of several days of price riots that claimed 247 lives by official count and injured nearly 2,000. The curfew had been imposed Feb. 28, a day after riots and looting erupted when authorities announced steep price boosts for transport fares, gasoline and some basic food items. Primary schools and kindergartens resumed classes, and secondary schools are expected to reopen this week. It was unclear when universities--traditionally a center of protest in Venezuela--will resume classes. Under martial law, soldiers can search houses without warrants and detain suspects without charge.
