WATCH: Spicer addresses Syria attack in news briefing

White House Press Secretary Sean Spicer is expected to field questions about last week’s U.S. strike on Syria in a Monday news briefing.

Watch Spicer’s remarks live in the player above.

A U.S. military spokesman said earlier today the U.S. has taken extra defensive precautions in Syria in anticipation of possible retaliation against American forces for last week’s cruise missile attack on a Syrian air base.

The spokesman, Col. John J. Thomas, told reporters at the Pentagon that the increased emphasis on defensive measures to protect U.S. troops on the ground in Syria led to a slight and temporary decline in offensive U.S. airstrikes against the Islamic State in Syria.

Thomas said there has been no Syrian retaliation for the cruise missile attack, which he said destroyed or rendered inoperable more than 20 Syria air force planes.

He said the U.S. intends to return to full offensive air operations as soon as possible.
