A Lebanese minister says the Cabinet has reversed measures against Hezbollah militants that triggered the worst violence since the country’s 15-year civil war.

Hezbollah has demanded the government reverse the decisions last week to sack an airport security chief for alleged ties to the Shiite group and to declare the militants’ private telephone network illegal.

Hezbollah leader Hassan Nasrallah said the moves amounted to a declaration of war and shortly after, he unleashed his fighters on the streets of Beirut. The clashes left 54 dead.

Information Minister Ghazi Aridi said the Cabinet revoked the decisions “in view of the higher national interest.”

Seconds after his announcement, celebratory gunfire erupted south of Beirut, a Hezbollah stronghold.
