A release issued by the White House stipulates that the president had been briefed "several times" throughout the day on the "latest developments" in the region.
"He has directed the Pentagon to assess and adjust as necessary US force posture in the region to enhance deterrence, ensure force protection, and support the full range of US objectives," the notice reads.
Biden had also directed his team to ensure that US embassies in the region "take all protective measures as appropriate."
The American commander-in-chief's orders were issued just as news broke of a second spate of airstrikes were conducted by the Israeli military late Friday. The latest operation saw the Israel Defense Forces (IDF) conduct targeted strikes on weapons reportedly belonging to the Lebanese Shia movement Hezbollah.
"The IDF is currently conducting targeted strikes on weapons belonging to the Hezbollah terrorist organization that were stored beneath civilian buildings in the area of Dahieh in Beirut," the IDF said on Telegram.
A Sputnik correspondent reported that explosions had been heard as smoke appeared from the southern suburb of the Lebanese capital. Earlier, similar strikes prompted 10 explosions to sound off.
Although figures are expected to rise, the death toll presently stands at six and 91, according to the Lebanese Health Ministry's emergency center.
Earlier Friday, Israel said that it had carried out an airstrike on the main headquarters of the Lebanese movement Hezbollah in Beirut, destroying several residential buildings in the attack. The Al Arabiya broadcaster reported that Israel tried to eliminate Hezbollah leader Hassan Nasrallah, but failed.
