WARSAW - Poland's government has adopted a resolution to increase ammunition production, the prime minister said on Wednesday, as Ukraines allies seek to increase supplies ahead of a possible spring offensive.

"I encourage private companies, state companies, foreign entities ... to quickly take up the challenge to create new ammunition production plants on Polish territory," Mateusz Morawiecki told a news conference.

"We want to allocate 2 billion zlotys ($463.32 million) for investments from the budget." ($1 = 4.3167 zlotys)
