A half-hour ago, a taxicab exploded in front of St. Patrick's on Fifth Avenue, where the Pope is scheduled to deliver Mass this weekend. WNBC reports that there is "a dark plume of smoke rising high above the church," and that a large crowd of onlookers has gathered. Right now it seems as though it was just a rogue combustion like last fall's 30 Rock explosion. We'll keep you posted if we hear more.
