A person is used as a human shield from gunfire, and is thus riddled with bullets, and several bloody bullet holes can be seen.
Violent fights, explosions and shootings resulting in visible blood, though no close-up shots of serious wounds.
A few references of sadomasochism (one of the main antagonists gains sexual pleasure from beating women).
A car explodes with some men trapped inside.
One torture scene (a man is tied up and beaten several times. His two toes are then struck by a hammer, offscreen but still heard and heavily implied.)
A flat is blown up by a bomb, several men are inside.
