NATO has called on its member states to authorize Ukraine to use Western weapons against military targets in Russia during a spring session in the Bulgarian capital Sofia on Monday.
NATO's Parliamentary Assembly (PA) adopted a corresponding declaration vowing support of Ukraine until victory is achieved.
The time has come to lift some restrictions on the use of the weapons provided, NATO Secretary General Jens Stoltenberg said.
Stoltenberg cited the Ukrainian region of Kharkiv, where the front line and the border with Russia more or less coincided, as an example of a possible use of Western weapons.
Ukraine would be weaker if NATO members continued to support it only halfway, warned the president of NATO's Parliamentary Assembly, Michał Szczerba from Poland.
Ukrainian Defence Minister Rustem Umerov appealed in a video message for the allies to close the airspace over western Ukraine with their air-defence systems.
Umerov reiterated that his country was striving for full NATO membership.
Parliamentarians from NATO member countries and partner states took part in the PA spring meeting. A delegation from the German Bundestag also travelled to Sofia.
Stoltenberg named three topics for the upcoming NATO summit in Washington in July: improving the defence capabilities of member states, support for Ukraine and global partnerships with a focus on the Asia-Pacific region.
The Parliamentary Assembly also called for the creation of a centre at NATO headquarters in Brussels to combat disinformation.
