June 7 (UPI) -- Iran on Sunday launched air strikes at Israel for the first time since the beginning of a fragile cease-fire, which it said was in response to Israeli strikes in Lebanon.

The missiles, which the Israel Defense Forces said had been intercepted, are the first direct attack on Israel since a cease-fire went into effect on April 8 that has mostly paused the war in Iran, The BBC, The Guardian and Axios reported.

The attacks follow an announcement on Sunday that Israel had launched strikes at alleged Hezbollah targets in Beirut -- attacks which it has continued throughout the cease-fire -- and some of which have been in suburban neighborhoods.

U.S. President Donald Trump, who reportedly has been briefed on Iran's actions, told Iran "that's enough, get back to the table" for peace negotiations, Fox News reported.
