<h1>Campaign motorcade pelted with rocks and bottles, forcing evacuation as aide and relative linked to leaked bribery audio attended</h1> A presidential campaign caravan in Buenos Aires province was disrupted when protesters hurled rocks, bottles and other objects at the motorcade, injuring no one but forcing an early evacuation; security agents shielded the president and entourage, including a relative and senior aide implicated in a separate corruption scandal based on leaked audio alleging bribery. The governing party blamed followers of a powerful former president, who is banned from politics and under house arrest following a corruption conviction. The incident heightens tensions ahead of provincial and national elections and may factor into ongoing criminal investigations and political liability for implicated officials.
