Dramatic scenes from Colombia show a police helicopter crashing into a mountain after reportedly being struck by a drone, just hours after a deadly car bomb explosion rocked a military air base in Cali. The back-to-back attacks, which killed at least 17 people including police officers and civilians, have sent shockwaves through the country. President Gustavo Petro condemned the acts as terrorism, pointing to possible involvement of the notorious Gulf Clan cartel.
