Israel-Gaza-Lebanon live updates: Crisis in Gaza mounts as medicine, supplies blocked

The United Arab Emirates' Interior Ministry said Monday it arrested three Uzbek nationals suspected of the kidnapping and killing of Moldovan-Israeli rabbi Zvi Kogan.

Kogan, 28, was an ultra-Orthodox rabbi who went missing on Nov. 21. He managed a kosher grocery store in Dubai.

The ministry identified the three detained men as Olimpi Tohirovic, 28, Mahmoud John Abdul Rahim, 28, and Azizi Kamilovic, 33. It did not say whether charges had been filed and did not suggest a motive.

Israeli leaders have framed the killing as an antisemitic terror operation. Prime Minister Benjamin Netanyahu said Sunday his nation would "act by all means" to "bring justice to the murderers and their senders."

Israel Defense Forces spokesperson Avichay Adraee said on Monday morning that Israeli warplanes would soon begin new airstrikes in Beirut, following 24 hours of intense bombing of the city's southern suburbs.

Adraee ordered residents of the Haret Hreik area of the southern Dahiya suburbs -- known as a Hezbollah stronghold -- to flee their homes and stay at least 500 meters from target buildings identified on an IDF map.

There were more strikes Sunday night in the southern suburbs of Beirut, which have been pounded by dozens of Israeli strikes in the last few days.

The Israel Defense Forces said Sunday night's strikes in Dahieh were on "12 Hezbollah command centers."

The death toll from an Israeli strike Saturday in central Beirut has risen to 29, according to the Lebanese Ministry of Health.

The update on casualties came as emergency workers continued to search collapsed buildings for survivors of the strike, an official said.

At least 67 people were also injured in the Israeli strike, according to the Ministry of Health.
