Venezuela's National Guard has fired tear gas on residents who were clearing a barricaded border bridge between Venezuela and Colombia to let humanitarian aid pass through.
The tensions flared early on February 23 at the blocked entrance of the bridge on the Venezuelan border town of Urena.
Opposition leader Juan Guaido has vowed to bring humanitarian aid across into Venezuela from Colombia over objections from President Nicolas Maduro.
Venezuelan officials have ordered the border with Colombia closed after already shutting down crossings from Brazil and the island of Curacao, other points of entry for the aid.
But the residents in Urena have defied government orders and began removing yellow metal barricades and barbed wire.
