(The other prelates are wearing white too. When in Rome I wish he'd go back to black.)
Even North Korea welcomed him.
Upon his arrival in South Korea, Francis was welcomed by President Park Geun-Hye and also by three rockets. The Pope flew into Incheon airport in Seoul at 10:15 (local time) this morning for a five-day visit. North Korea fired three short-range rockets from a 300-millimeter multiple rocket launcher, into the East Sea (Sea of Japan), shortly before the Pope’s arrival. This is according to South Korea's Ministry of Defence.
The rockets were fired at a range of 220 kilometres from a launch site near Wonsan, a city on the north-eastern coast and ended up in the East Sea. The launches began at 9:30 without any prior warning and continued for about 25 minutes. - Source
