Watch live: White House holds press briefing amid Israel-Hamas conflict

White House press secretary Karine Jean-Pierre is set to hold the daily press briefing Wednesday afternoon alongside National Security Council Coordinator for Strategic Communications John Kirby.

President Biden on Tuesday harshly condemned the “abhorrent” terrorist attacks over the weekend by Hamas as the death toll in the region climbed, vowing that the U.S. would fully support the Israeli people.

The president also confirmed that Americans are among those being held hostage, with officials saying as many as 20 Americans are unaccounted for.

Both Biden and his top national security adviser, Jake Sullivan, backed Israel’s right to respond with force, as Israeli forces prepared to go on the offensive, and signaled an upcoming push for Congress to provide additional support.

In addition to the Israeli casualties, hundreds of Palestinians have been killed in Gaza amid relentless bombings by Israel, which vowed retaliation for the unprecedented attack. More than a dozen American citizens have been killed, according to the White House.

The event is scheduled to begin at 1 p.m EDT.
