As Ukraine battles to deter Russia's offensive around Kharkiv, the debate around restrictions on the use of weapons donated by NATO countries continues.
The US is coming under increasing pressure to drop its ban on Ukraine using its weapons to hit targets inside Russia.
President Joe Biden and co have been worried that allowing Ukraine to do so would be seen as escalation by Moscow.
Ukraine was forced to watch as Russian troops amassed across its northern border, unable to bring its full weaponry to bear.
With the debate in full swing - and the US reportedly considering a change - Sweden has confirmed that Ukraine can use its weapons against targets in Russia.
Defence minister Pal Jonson told Swedish newspaper Hallandsposten that no such rule applied to his country's weapons.
He said: "Ukraine is exposed to an unprovoked and illegal war of aggression by Russia.
"According to international law, Ukraine has the right to defend itself by means of hostilities aimed at the territory of the adversary as long as the hostilities comply with the laws of war.
"Sweden stands behind international law and Ukraine's right to defend itself."
