Saturday night's sirens came after the IDF struck two Houthi-controlled ports in Yemen that were used to transfer weapons.
The warning was sent at 9:45 a.m. on Wednesday, following a similar warning against the Houthis on Sunday, in which the IDF also did not actually attack.
The last sirens that were sounded in the Israeli capital occurred 13 hours prior, also due to a missile launch from Yemen, and the third missile that fired towards Israel in two days.
Following the sirens, the IDF announced that the missile had been intercepted.
This follows President Donald Trump's Tuesday announcement that the US would stop bombing the Iran-aligned Houthis in Yemen, saying that the group had agreed to stop attacking US ships.
Senior Middle East analyst Seth J. Frantzman discusses what military capabilities the Houthis have after US strikes against them, and why they are so hard to fight.
Airport officials said that “the flight board has been updated, and the airlines have not canceled the slots.”
“We have no hostility toward neighboring countries, but American bases are targets for us if we are attacked," Iran's Defense Minister Aziz Nasirzadeh said.
Leading defense analysts say that the Houthis' latest attacks are Tehran showing what it is truly capable of.
"Washington now realizes that Israel can no longer remain passive," an Israeli official said.
