The Israeli military says it is investigating an apparent drone attack that hit central Tel Aviv in the early hours of Friday.
In a statement, it said an initial inquiry indicated the explosion had been caused by the falling of an "aerial target", which was not intercepted because of human error.
Israeli emergency services say the explosion left one person dead and several lightly injured.
Yemen’s Houthi militants have claimed responsibility for the attack.
The group - which is backed by Iran - announced earlier on social media that they would reveal details about a military operation that had targeted Tel Aviv.
The Israeli military added it was increasing air patrols, while the city's mayor said they were on high alert, local media reported.
"The whole building shook," Alon, a local resident, told Haaretz.
"My neighbours' windows shattered, so I was sure something had hit the building. It was only when I went outside that I realised that several buildings had been damaged."
The incident also came after the Israeli military confirmed it had killed a senior commander of the Hezbollah militia in southern Lebanon.
Hezbollah and Israel have traded fire across the border since Hezbollah launched rockets a day after Israel began its military offensive on Gaza in response to Hamas's deadly attack on Israel on 7 October.
Both Hezbollah and the Houthis say they are acting in solidarity with the Palestinians.
