As officials meet in Switzerland to negotiate the terms of a tenuous U.S.-Iran accord, and tensions reignite over the Strait of Hormuz, here's a look at what the conflict has already cost.

Israel has carried out strikes across southern Lebanon, despite a warning from Iran not to continue attacks in the country. The Lebanese health ministry said eight people were killed in Tyre, where the Israeli military issued a new order for residents to leave the southern city, including its Christian quarter for the first time. Israel and Iran paused hostilities on Monday, after an Israeli strike on Beirut targeting the Iranian-backed armed group Hezbollah triggered their first exchange of fire since a truce in April. Iran warned that it could hit Israel again if it did not stop attacks in Lebanon. But Israel vowed to continue its campaign against Hezbollah.

Starting in June, the health ministry will ban the manufacturing, sale, possession and use of the cannabis-derived compound cannabinol (CBN). Japan's health ministry is set to ban the production, sale, possession and use of cannabinol, or CBN, an ingredient derived from cannabis, from June. An animal experiment conducted following reports of apparent health hazards associated with CBN has found that the substance is highly likely to cause symptoms such as hallucinations. The ministry will regulate CBN as a designated drug under the pharmaceutical and medical devices law through a revision of a relevant ordinance. The amended ordinance is set to take effect in June. In a time of both misinformation and too much information, quality journalism is more crucial than ever.

The Israeli military has said it is carrying out air strikes on Hezbollah targets in Tyre in southern Lebanon, after ordering the evacuation of the entire city. The military told residents that it was compelled to act forcefully in Tyre because the Iran-backed armed group was violating a US-brokered ceasefire that began five weeks ago. Earlier on Wednesday, Lebanese media reported a wave of Israeli strikes across the south and the eastern Bekaa Valley, with four people killed in the towns of Choukine and Nabatieh. Hezbollah, which has itself accused Israel of breaching the ceasefire, said it was battling Israeli troops north of the Litani river, about 30km (19 miles) from the border. It came a day after Israel's prime minister announced an expansion of its ground operation following Hezbollah drone attacks on troops occupying part of southern Lebanon and on civilians in northern Israel.

Israel has launched an intensive wave of strikes across swathes of southern and eastern Lebanon, after vowing to step up its military action against Hezbollah. The Israeli military said it hit more than 100 Hezbollah infrastructure sites and fighters during what was one of the heaviest nights of bombardment since a US-brokered ceasefire began in mid-April. Strikes in the Bekaa Valley village of Mashghara killed 11 people, including two children, Lebanon's health ministry said. The military said it hit sites where terrorist activity was identified. It came after Israel's Prime Minister Benjamin Netanyahu said he had given the instruction to press the pedal even harder in targeting Hezbollah.

Israeli air strikes have killed at least 19 people in southern Lebanon, the country's health ministry has said. Ten of them, including three children and three women, were killed in a single attack that hit a house in the town of Deir Qanoun, the ministry said. Lebanon was drawn into the war on 2 March, when the Iran-backed armed Shia Islamist group Hezbollah fired rockets at Israel in retaliation for US-Israeli strikes that killed Iran's supreme leader. The latest deaths less than a week after the US said that Lebanon and Israel had agreed to extend a ceasefire by 45 days, with the two sides set to resume talks at the beginning of June. Despite the extension, both Israel and Hezbollah have continued to exchange fire, especially in southern Lebanon.

Hezbollah has increased its use of small first-person view (FPV) drones to attack Israel, including systems controlled by fibre-optic cables to evade sophisticated defences. BBC Verify has geolocated 35 videos shared by the Lebanese armed group since 26 March which show strikes on Israeli soldiers, armoured vehicles and air defence systems in southern Lebanon and northern Israel. Experts told BBC Verify the Israel Defense Forces (IDF) has so far been unable to develop any effective countermeasures, as the small drones can easily bypass detection systems. The drones can also be made from commercially available and 3D-printed components - and are cheap compared to the high-value targets they can destroy, experts also said. The use of cheap FPV drones became widespread during the Russia-Ukraine war and has changed modern warfare.

At least nine people, including two children, were killed in Israeli strikes in southern Lebanon on Thursday, the health ministry said, as violence continues despite a ceasefire now in its second week. The strikes - which Israel said were targeting Hezbollah infrastructure - also wounded 23 people, among them eight children and seven women, the ministry said. Separately, Hezbollah said it had carried out attacks on Israeli forces in the south, including a drone strike targeting soldiers in the Bint Jbeil district. The violence comes as Israel presses ahead with military operations in Lebanon despite the ceasefire announced on 16 April, after direct talks between Lebanese and Israeli ambassadors in Washington. Lebanese President Joseph Aoun criticised what he described as continuing Israeli violations of the truce, saying strikes and demolitions of homes and places of worship were ongoing despite the ceasefire.

Israeli strike on Yemen's Houthis reportedly kills eight The Israeli military says its air force has carried out its most powerful strike in Yemen in response to the Houthi movement's repeated drone and missile attacks on Israel. The Israel Defense Forces (IDF) said dozens of its aircraft bombed targets belonging to the Houthis' security and intelligence services, and military in the capital Sanaa. The Houthi-run government's health ministry denounced what it called Israel's brutal crime, saying civilian facilities and residential buildings were hit and that eight people were killed. It comes a day after 22 people were injured, two of them seriously, in a Houthi drone attack in the Israeli Red Sea resort of Eilat. The Houthis have controlled much of north-western Yemen since they ousted the country's internationally recognised government from there 10 years ago, sparking a civil war.

Italy condemns'drone attack' on Gaza aid flotilla and deploys frigate Italy's defence minister has condemned what he said was an overnight drone attack by unidentified perpetrators on a flotilla trying to breach Israel's naval blockade of Gaza to deliver aid. Guido Crosetto also said he had ordered an Italian Navy frigate to head towards the 52 boats in the Global Sumud Flotilla (GSF), which are mostly off the coast of Crete, to assist Italian citizens on board. The GSF said several boats reported explosions and unidentified objects being dropped, as well as drones overhead and communications jamming. It accused Israel of a dangerous escalation. Israel's government has not commented.
