An Italian surfer has died in a rare and tragic accident after being struck by a swordfish while surfing off Indonesia's West Sumatra coast.
Giulia Manfrini, 36, was fatally injured after a swordfish speared her in the chest while she surfed in the waters off Ombak Bengbeng, near Masokut Island, according to local authorities.
Lahmudin Siregar, acting head of the Mentawai Islands' Disaster Management Agency, said the swordfish "unexpectedly jumped towards Manfrini and pierced her chest".
