Explosion heard at Yasukuni Shrine: media

An explosion was heard at Japan's controversial war-linked Yasukuni Shrine in downtown Tokyo at around 10 a.m. local time on Monday, local media reported, adding there was no injuries. The explosion site was found in a toilet around the shrine's south gate, with parts of the toilet's walls and ceilings were damaged, according to Japan's public broadcaster NHK. The report said local police and fire authorities are investigating in the incident. Yasukuni enshrines 14 convicted Class-A Japanese war criminals during the World War Two and is considered as the symbol of the country's past militarism. Continuous visits to the shrine by Japanese ministers and lawmakers have become a major obstacle for Japan to mend its ties with its two closest neighbors of China and South Korea, both of whom were suffered from Japan's wartime aggression.
