In April this year, the US finally approved a long-awaited aid package worth some $60.8bn (£49bn) in aid to Ukraine.
Included were vast quantities of much-needed weapons and ammunition meant for the frontlines – which Kyiv had been desperately calling for for months.
So how have they impacted the war?
Nichita Gurcov, Eurasia analyst for Armed Conflict Location & Event Data Project (ACLED) told Sky News it may actually have pushed Moscow to act quickly and launch fresh attacks.
“It may have prodded Russia to step up its offensive to claim as much ground as possible, before the arriving weapons make it harder,” he says.
Russia resumed its offensive in October last year after fending off the latest Ukrainian attempt to cut the land corridor to Crimea, Gurcov explains.
“By mid-February [this year] Russia secured the Avdiivka stronghold and has been since pressing toward Ukrainian logistical hub in Pokrovsk,” he said.
ACLED has counted the number of settlements gained by Russia in each month of the conflict.
Five were taken in February, but just two in March.
In April (the month the US aid package was announced), seven settlements were captured, followed by nine in May and 11 in June – highlighting a clear increase in Russian offensive action.
“The sharp increase in the number of claimed settlements in May is due to the Russian re-invasion of the northern Kharkiv region,” Gurcov explains.
“It could have pursued – diverting Ukrainian forces from elsewhere – but so far has been contained,” he adds (see 11.40am post).
Another indicator of increased fighting is the number of reported battles, according to ACLED:
“The sharp increase in fighting in April and the subsequent near-50% increase in May is an all-time high since the invasion,” Gurcov notes.
“The spike is only partially due to the re-invasion of the Kharkiv region as we are recording steadily intensifying offensive in the Donetsk region,” he adds.
