Poland's President Andrzej Duda on Wednesday said it was "very likely" that the deadly missile that struck a Polish border village was from Ukraine's air defence.

"Absolutely nothing indicates that this was an intentional attack on Poland... It's very likely that it was a rocket used in anti-missile defence, meaning that it was used by Ukraine's defence forces," he told reporters.
