Israel launched airstrikes against targets in the suburbs of Beirut on Sunday, marking a sharp escalation in the conflict with Hezbollah.
The Israeli military stated the operation was a direct response to recent attacks by the Lebanese militant group.
According to Lebanese health officials, the strikes resulted in at least one fatality.
The development arrives amid heightened regional volatility, as markets remain sensitive to any disruption in Middle Eastern energy flows.
The strikes intensify pressure on the already fragile ceasefire between the United States and Iran, which has been under strain since Tehran reportedly launched missiles at Israel earlier in the week.
Investors are for signs of a broader regional conflagration that could threaten oil supply routes.
