Two men in their twenties have been killed in the latest in a string of gang shootings in Stockholm, police said.
The men were shot dead late on Wednesday while sitting in a car in a residential area of Kista, north-west of the Swedish capital.
Police believe the killing is in connection with an on-going feud between criminal gangs over territory.
In just over two months – since the start of 2017 – there have been 17 shootings in Stockholm.
The incidents have left seven dead - including five this week - and 14 injured, local police chief Ulf Johansson said.
Gang members have used Kalashnikov-style rifles and hand grenades in the attacks which relate to feuds over drug markets and territory.
"These are young men with access to weapons," Mr Johansson said. "This is of course alarming and very serious.”
Mr Johansson said police in the Swedish capital had asked for extra resources but did not give details.
No suspects have been arrested after the overnight shooting and the motive was not known.
Swedish broadcaster SVT and the Expressen tabloid said one of those killed late on Wednesday was a leading member of the Lion group, which it described as well-known for its drug-linked criminal activities.
SVT said the Lions were in conflict with the Wolfpack Brotherhood and the shooting may be linked to that.
Police declined to comment on the ongoing investigation.
Swedish media said the victims were shot in the head several times, adding investigators would look at previous incidents in the area
