Bolivians languished in long lines on the streets of La Paz on Sunday to secure chicken, eggs and cooking fuel as supporters of ousted President Evo Morales crippled the country's highways, isolating population centers from lowland farms.

Presidency minister Jerjes Justiniano told reporters the government of interim President Jeanine Anez had established an "air bridge" to supply La Paz, using planes to bypass barricades on highways surrounding the highland capital. He said officials hoped to do the same with other cities cut off from supplies.

Bolivia remained in limbo one week after Morales, a charismatic leftist and former coca farmer, resigned over allegations of vote-tampering. Lawmakers have yet to agree on a date for new elections.
