WASHINGTON (AP) — House Speaker Mike Johnson left uncertain his plan for advancing aid for Israel and Ukraine on Monday, keeping the future of the funding in doubt as lawmakers returned to Washington for a crucial week of foreign policy work.

Iran’s missile and drone strike against Israel over the weekend put renewed pressure on House Republicans to act on a national security package that would send military support to Ukraine, Israel and Taiwan. But after mulling for two months how to advance such a package through the political divides in the House, Johnson has revealed little of his strategy, including whether he will try to push the funding for Israel separately or keep it packaged with the aid for the other U.S. allies.

As the House has struggled to act, conflicts around the globe have escalated. Israel’s military chief said Monday that Israel will respond to Iran’s weekend missile strike. And Ukraine’s military head over the weekend warned that the battlefield situation in the country’s east has “significantly worsened in recent days,” as warming weather has allowed Russian forces to launch a fresh offensive.
