Russia could fire its new Oreshnik hypersonic missile at the Ukrainian capital Kyiv in response to Ukraine's strikes on its territory, President Vladimir Putin said Thursday.

Yemen’s Houthi rebels will keep up their attacks on Israel, their leader said on Thursday, two days into a ceasefire in Israel’s war with Hezbollah in Lebanon.

"The operations from the Yemeni front to support the Palestinian people with missiles and drones towards the Israeli enemy are continuing," Abdulmalik Al-Huthi said on the rebels’ Al-Masirah TV station.

The Israeli military announced a new nighttime curfew in parts of south Lebanon Thursday, a day after a ceasefire with Hezbollahbegan.

Two airstrikes targeted an area in the Sidon district on Thursday afternoon, Lebanese TV networks said.

The Israeli army said a warplane carried out an airstrike after "terrorist activity was detected at a Hezbollah facility containing medium-range rockets in south Lebanon."

Lebanon's military deployed troops and tanks across the country's south on Thursday as a ceasefire in the Israel-Hezbollah war largely held for a second day.

The truce ended a war that began a day after Hamas's unprecedented October 7, 2023 attack on Israel, killing thousands in Lebanon and sparking mass displacements in both Lebanon and Israel.

Hezbollah said Wednesday it had achieved "victory" over Israel and that its fighters were at the ready, after a truce between the two sides took effect.

"Victory from God almighty was the ally of the righteous cause," a statement from the Iran-backed group said, adding that its fighters "will remain in total readiness to deal with the Israeli enemy’s ambitions and its attacks".

Parliament will meet on January 9 to elect a new president, seeking to end more than two years without a head of state, official media reported Thursday, a day after an Israel-Hezbollah ceasefire began.

The official National News Agency also reported that parliament on Thursday extended the mandate of army chief Joseph Aoun, himself floated as a potential presidential contender.

The U.N. peacekeeping force in Lebanon (UNIFIL) welcomed the ceasefire between Israel and Hezbollah on Wednesday, saying it had begun adjusting operations to the "new situation".

"We will continue performing our mandated tasks, and we have already begun adjusting our operations to the new situation," UNIFIL said in a statement, adding that peacekeepers "stand ready to support Lebanon and Israel in this new phase".

The Israeli army announced restrictions Wednesday on people's movements in south Lebanon after dark, hours after a ceasefire with Hezbollah took effect.

Residents will be barred from travelling south of the Litani River, some 30 kilometers from the border, between 1500 GMT and 0500 GMT Thursday, military spokesman Avichay Adraee said in a post on X. They will also be barred from returning to villages the army has ordered evacuated, he added.

U.S. President Joe Biden will launch a renewed drive Wednesday for a Gaza ceasefire and hostage release deal, now that Israel and Hezbollah have agreed to a truce in Lebanon, his national security adviser said.

The truce that began before dawn Wednesday in the south Lebanon war means Iran-backed Hezbollah is no longer fighting in solidarity with Hamas in Gaza. That will increase pressure on the militant Palestinian group to agree to a ceasefire and hostage deal, Jake Suillivan told MSNBC.
