Volodymyr Zelenskyy and Alexander De Croo sign new security pact.

Ukraine and Belgium have signed a security agreement which includes the delivery of 30 U.S.-made F-16 fighter jets, in a move to bolster Kyiv’s defense capabilities against Russian President Vladimir Putin’s ongoing invasion.

Volodymyr Zelenskyy and Belgian Prime Minister Alexander De Croo agreed on a plan that “includes at least €977 million in Belgian military aid to Ukraine this year,” the Ukranian  president announced Tuesday, during a visit to Belgium.

De Croo had already announced last year that Belgium would send F-16s to Ukraine in 2025 — without saying how many. Crucially, he also said at the time that the main condition would be whether the next government also agrees to do so, as Belgium is headed toward an election in June.
