Nigeria has lifted a law which forced hospitals to withhold emergency treatment from victims of gun attacks until a police report had been filed.
Officials revoked the law, in place since the 1980s, over concerns about a rising death rate from bullet wounds.
It comes weeks after newspaper editor Bayo Ohu died from bullet wounds after a hospital reportedly waited for a police report rather than treat him.
Nigeria is notorious for gun-related crime including kidnapping and robbery.
Earlier this year its commercial capital, Lagos, topped a poll of the world's most dangerous places to work.
The BBC's Raliya Zubairu, in Abuja, says the government is threatening to withdraw the licences of any clinics failing to abide by the new ruling.
