CARACAS (Reuters) - Venezuela’s President Nicolas Maduro said on Tuesday that a police helicopter had attacked the Supreme Court in Caracas but a grenade tossed at the building did not explode.

Speaking on state TV, the 54-year-old president, who has been facing three months of opposition protests and some dissent from within government ranks, said that Venezuelan special forces were after the “terrorists” behind the attack.
