The Venezuelan National Assembly swore in grassroots leader Juan Contreras to assume the vacant post of the late deputy Robert Serra on October 7. Serra, a 27-year-old socialist deputy, was stabbed to death alongside his partner Maria Herrera in their Caracas home on October 1. Legislators also voted to ban former right-wing Colombian president Alvaro Uribe from entering Venezuela. Venezuelan President Nicolas Maduro has accused Uribe of being linked to the killings.
