An explosion in northern Peru has injured at least 10 people and damaged 25 homes. Authorities on Friday said the blast in Trujillo on Thursday night might be linked to criminal groups involved in extortion, which has been on the rise in recent years across the country. The explosion also disrupted electricity and affected vehicles. It was the second blast reported Thursday, following one at a gym in Lima. Explosive attacks are now common in Peru, with incidents often targeting small businesses. The La Libertad government admits crime sometimes overwhelms police efforts.
