The Group of Seven (G7) economic powers said on Monday they would work together to bolster Ukraine's military capabilities, with an immediate focus on air defense systems, according to a leaders' statement released by Britain.

"We will continue to coordinate efforts to meet Ukraine's urgent requirements for military and defense equipment with an immediate focus on providing Ukraine with air defense systems and capabilities," the statement said.

Specific weapons deliveries to Ukraine were not on the agenda, a spokesperson for the German government, which holds the G7 presidency, said ahead of the meeting.
