The mission demanded a full and immediate investigation by Lebanese authorities and for all perpetrators to be brought to justice, it said in a statement.

Lebanese state news agency NNA reported interior minister Ahmad al-Hajjar called for an emergency meeting before noon today to discuss the security situation.

“He affirmed the Lebanese government’s rejection of this assault that is considered a crime against Unifil forces,” NNA reported, citing the Lebanese minister.

He also gave instructions to work on identifying the perpetrators and referring them to the relevant judicial authorities.

The US condemned the attack that it said wounded UN peacekeepers.

The state department statement said the attack was carried out “reportedly by a group of Hezbollah supporters”, referring to the Iran-backed resistance group in Lebanon.
