The attack raised concerns that the cease-fire that ended a war between Israel and Lebanese militants might be in jeopardy.

BEIRUT (Reuters) -The Israeli army said on Sunday it struck a southern Beirut building being used to store precision missiles belonging to Hezbollah. The attack was a further test of a fragile ceasefire between Israel and the Iranian-backed militant group.

The attack "raised concerns that the ceasefire that ended a war between Israel and Lebanese militants might be in jeopardy," The New York Times said. The U.S. has pushed Lebanon to disarm Hezbollah, but Aoun has cautioned that the "delicate" issue must be handled carefully to maintain peace. Hezbollah has insisted it will not give up its weapons.
