The strikes targeted "a military compound used by Hezbollah's aerial unit" in the Baalbek District which is in the northeast of the country.

This marks the deepest Israeli strike inside Lebanon since the war began in the wake of the Oct.7 Hamas terror attack, at more than 110km from Israel's border.

The extent of casualties or damage remains unclear, but it follows a similar February strike on the Bekaa Valley some 100km from the Israeli border, which killed at least two people. There are growing fears that if such strikes become more regular, it will signify a bigger regional war could be opening up.

Hezbollah has lobbed several missiles against northern Israeli communities as well as the IDF base atop Mount Meron over the past days. The Mount Meron surveillance base is about 8km from the Lebanese border and has come under repeat attack over several months.

In the overnight and early morning hours there were also large-scale strikes against areas of eastern Syria. While Israel frequently attacks Syria, some Syrian government-affiliated sources laid blame on the United States. According to regional outlet The Cradle: 

Airstrikes targeted a number of areas in Syria's eastern city of Deir Ezzor and its countryside on 26 March, resulting in numerous deaths and injuries. "At 1:49 AM, American aircraft carried out several simultaneous air strikes targeting a number of areas in the governorate and its countryside," Syria's government-affiliated National Defense Forces (NDF) said, according to Sputnik.

The strikes targeted the Salhiya area in Al-Bukamal near the Iraqi border and residential areas in the Al-Mayadin and Al-Qusour areas in Deir Ezzor.
