American citizens are among those captured by Hamas terrorists, President Joe Biden confirmed on Tuesday, and Hamas has killed at least 14 Americans so far in their terror attacks against Israel.

Hamas terrorists invaded Israel on Saturday, on the 50th anniversary of the 1973 Yom Kippur War. Pro-Palestinian terrorists have murdered more than 1,000 Israeli citizens, and wounded thousands more.

Flanked by Vice President Kamala Harris and Secretary of State Anthony Blinken, Biden said that the U.S. unequivocally stands with Israel, and will make sure the country can defend itself against the “hatred and violence” of Hamas terrorists.

The president failed to mention Hamas’s connection to Iran, which is the terrorist group’s primary financial backer and, according to the Wall Street Journal, was heavily involved in planning and providing the resources for the weekend attack.

The Hamas attack came weeks after the Biden administration unfroze $6 billion in Iranian funds being held in Qatari banks in exchange for the release of five American prisoners from Iranian custody. Members of the GOP have called on Biden to freeze the funds or re-issue them to Israel, pointing out that the funds, which the administration insists can only be used for humanitarian purposes, help free up the Iranian regime to further fund terror in the region.

Biden denounced Hamas’s “abhorrent” terrorism, adding that the U.S. would send ammunition and interceptors to replenish Israel’s Iron Dome defense system. When Congress returns to session, he added, Biden will ask Congress to fund Israeli defense efforts.
