Sweden and Canada have said they will resume aid payments to UNRWA, the UN agency for Palestinian refugees.
They were among 16 countries that paused funds after Israel accused at least 12 UNRWA staff of involvement in the 7 October attack by Hamas.
The UN is investigating, and France’s foreign minister is leading a review.
Sweden said on Saturday it would send $19m initially, after UNRWA agreed to more checks on its spending and staff.
It comes after Canada said on Friday that it would re-start funding for UNRWA while investigations into the agency’s staff continue.
On 7 October, Hamas gunmen stormed across Gaza’s border into Israel, killing about 1,200 people and taking more than 250 hostage.
In response, Israel launched a campaign of air strikes and a ground invasion of the territory.
More than 30,900 people have since been killed in Gaza, the territory’s Hamas-run health ministry says, and the amount of aid reaching civilians has plummeted.
The UN has warned that a quarter of the Strip’s population is on the brink of famine and children are starving to death.
UNRWA is the biggest UN agency operating in Gaza. It provides healthcare, education and other humanitarian aid, and employs about 13,000 people there.
