NATO marked on Thursday 75 years of collective defense across Europe and North America, with its top diplomats vowing to stay the course in Ukraine as better armed Russian troops assert control on the battlefield.

President Joe Biden has faced protests over the conflict in Gaza all over the country, but this week he confronted one inside the White House itself.

At least ten Iranian security personnel have been killed in two attacks claimed by a jihadist group in the country's southeast near Pakistan, state media reported on Thursday.

NATO chief Jens Stoltenberg said Wednesday that alliance members must guarantee long-term weapon deliveries for Ukraine, as ministers prepared to discuss a proposal for a 100-billion-euro, five-year fund.

"We must ensure reliable and predictable security assistance to Ukraine for the long haul so that we rely less on the voluntary contributions and more on NATO commitments, less on short-term offers and more on multi-year pledges," Stoltenberg said as NATO foreign ministers met in Brussels.
