Fight on French train involving axe and samurai sword leaves 4 students wounded, including one victim with hand cut off

Four teens were wounded, two of them seriously, by an axe wielded during a fight on Monday on a suburban train outside Paris, police sources said, with the main suspect later arrested.

One of the victims - all aged 16 or 17 - had a hand cut off and another had their skull split open.

Two others were more lightly injured in the struggle that one police source said had broken out around 8:00 am as the teenagers involved were on their way to secondary school.
