WASHINGTON (AP) — President Joe Biden is set to host Iraq’s leader this week for talks that come as tensions across the Middle East have soared over the war in Gaza and Iran’s unprecedented weekend attack on Israel in retaliation for an Israeli military strike against an Iranian facility in Syria.

The sharp rise in security fears has raised further questions about the viability of the two-decade American military presence in Iraq, through which portions of Iran’s Saturday drone and missile attack on Israel flew or were launched from. A U.S. Patriot battery in Irbil, Iraq, knocked down at least one Iranian ballistic missile, according to American officials.

In addition, Iranian proxies have initiated attacks against U.S. interests throughout the region from inside Iraq, making Monday’s meeting between Biden and Iraqi Prime Minister Shia al-Sudani all the more critical. The talks will include a discussion of regional stability and future U.S. troop deployments but will also focus on economic, trade and energy issues that have become a major priority for Iraq’s government, according to U.S. officials.
