Venezuela's Supreme Court has been attacked by grenades dropped from a stolen police helicopter, in what President Nicolás Maduro called a ‘terrorist attack’. The court is regularly criticised by the Venezuelan opposition for its rulings which bolster Mr Maduro's hold on power. The policeman who piloted the helicopter issued a statement denouncing the ‘criminal government’. His whereabouts are unknown. Four grenades were dropped on the court, and 15 shots were fired at the interior ministry; one grenade failed to detonate. No injuries were reported. The pilot said on Instagram: ‘We don't belong to any political tendency or party. We are nationalists, patriots and institutionalists. The fight is not against the security forces but is against the impunity of this government. It is against tyranny.’ There is a question as to whether this attack might be a prelude to a coup attempt.
