Les Nations Unies expriment leur préoccupation concernant un incident de pulvérisation chimique sur la Ligne bleue du Liban
Les Nations Unies ont réitéré leurs préoccupations vendredi face aux rapports indiquant que les forces israéliennes ont pulvérisé des herbicides sur des zones au nord de la Ligne bleue séparant le Liban d'Israël le 1er février. Ce développement pose un « risque humanitaire sérieux » pour les civils vivant là-bas, a déclaré le Bureau du Haut-Commissariat aux droits de l'homme (OHCHR), lors d'un briefing avec les journalistes à Genève.
« L'utilisation d'herbicides soulève des questions sur les effets sur les terres agricoles locales et sur la manière dont cela pourrait affecter le retour des civils dans leurs foyers et leurs moyens de subsistance à long terme », a déclaré Alessandra Vellucci, Directrice du Service de l'information des Nations Unies à Genève.
Répétant la réaction à l'incident par le porte-parole du Secrétaire général des Nations Unies à New York jeudi, Mme Vellucci a souligné les obligations de toutes les parties en vertu du droit humanitaire international. « Toute activité de l'IDF au nord de la Ligne bleue est une violation de la Résolution 1701 », a-t-elle déclaré aux journalistes.
Le porte-parole de l'OHCHR, Thameen Al-Kheetan, a insisté sur le fait que les rapports nécessitaient une enquête plus approfondie « pour confirmer la nature des substances chimiques » utilisées. « Les attaques sur les terres agricoles et les sources d'eau posent un risque humanitaire sérieux », a-t-il poursuivi.
Le bureau des droits de l'homme des Nations Unies a également exprimé une profonde préoccupation face aux développements en Cisjordanie occupée, avertissant que de nouvelles opérations et colonies israéliennes risquent de compromettre un État palestinien viable.
Depuis l'année dernière, des dizaines de milliers de Palestiniens ont été déplacés de force à travers la Cisjordanie occupée.
Cela inclut trois camps de réfugiés touchés par l'opération militarisée « Mur de fer » d'Israël qui a déraciné plus de 32 000 personnes des camps de Jénine, Tulkarem et Nur Shams. Ils ne peuvent toujours pas rentrer chez eux et beaucoup ont vu leurs maisons détruites par les forces israéliennes, a affirmé M. Al-Kheetan.
Les nouvelles opérations de sécurité israéliennes impactant les Palestiniens ont inclus une campagne à Jérusalem-Est occupée, y compris au moins deux opérations majeures ciblant deux communautés palestiniennes, selon le bureau des droits de l'homme des Nations Unies, OHCHR.
« Dans le camp de réfugiés de Shu'fat, ils ont perquisitionné des dizaines de maisons et de magasins, détenu au moins 25 Palestiniens, confisqué des biens et saisi 10 véhicules privés », a déclaré M. Al-Kheetan. « Dans une autre opération à grande échelle, ciblant le quartier de Kafr Aqab et les limites du camp de réfugiés de Qalandiya, les forces de sécurité israéliennes auraient démoli 70 structures palestiniennes. Cela semble être en préparation de projets de colonisation majeurs dans la région. »
Le porte-parole de l'OHCHR a noté qu'en décembre, les autorités israéliennes ont lancé des appels d'offres pour la construction de plus de 3 000 unités de colonisation dans la zone entre trois des centres urbains palestiniens les plus importants : Jérusalem-Est, Ramallah et Bethléem.
En réponse à une question sur le « plan E1 » israélien qui séparerait apparemment le nord et le sud de la Cisjordanie de Jérusalem-Est, M. Al-Kheetan a averti qu'il « risque de séparer les communautés palestiniennes les unes des autres et affecte donc sérieusement la viabilité d'un État palestinien... en fin de compte, toutes les colonies doivent être évacuées et l'activité de colonisation doit cesser. »

New data showing that rivers were at their lowest level for decades last year provides further evidence that the climate crisis is real and countries must act immediately to protect themselves from the increasing threat to communities and livelihoods, the UN World Meteorological Organization (WMO) said on Thursday.
The key findings from WMO’s State of Global Water Resources 2025 report covering the hydrological cycle and extreme events in the five-year period to last year:
Highlighting the long-term decline in the Earth’s freshwater storage and glacier melt, WMO Secretary-General Celeste Saulo explained that the planet’s water reserves used to act as a planetary “savings account” that absorbed the occasional dry season, avoiding a water crisis. “One of the central stories of the 2025 report is what is happening to that savings account? And the simple answer is that we are depleting it,” she told journalists in Geneva.
Groundwater reserves are equally stretched and have been in decline since 2014, WMO’s report states, with nearly two-thirds of monitored wells worldwide showing levels lower than the historical norm and indicating a shift “further toward deficit…not recovery”.
“At the same time, we are seeing more water-related disasters,” Ms. Saulo said, while also stressing that the currently strengthening El Niño “will increase the risk of drought in some areas, and flooding in others”.
Glaciers disappearing
In 2025, for the fourth consecutive year, every major glaciated region on Earth lost ice mass, leading to short-term hazards including floods and long-term water insecurity, according to WMO.
Responding to a question about whether the changing global water cycle might have contributed to the deadly Nepal-China flooding disaster, Ms. Saulo explained that melting ice and rock was just one factor in the chain of events that ultimately sent a massive and deadly wall of water and debris downstream on 26 August, killing at least 1,367 people.
“You asked if it could happen again? Absolutely; the problem in this region is that there’s 63,700 glaciers at the last count,” she told a Press Conference in Geneva. “Even if you’re looking with remote sensing with satellites at these glaciers, you might see some faults, you might see some slight shifting, that does not mean necessarily catastrophic collapse. So, in order to plan for this, it’s very, very difficult. But the international community is looking very hard at ways in which we can bring people together to solve some of these monitoring issues.”
Data indicates that glaciers shrank between 2023 and 2025 with cumulative losses of 1,400 gigatonnes of water – or about one third of annual fresh water needs.
Every major glacier region on Earth lost ice for the fourth consecutive year.
“All 19 glacier regions around the globe lost ice; in Central Asia, Iceland, the Russian Arctic and western Canada and the United States, it was among the three worst years on record,” said Wayne Jenkinson, WMO’s Director of Hydrology and Cryosphere.
Some regions with smaller glaciers such as Central Europe, the Caucasus, the western Canada and the United States may already have reached “peak water”, Mr. Jenkinson warned.
“After this point, the glacier gives less meltwater each year simply because there is less ice left to melt. That matters for every community downstream that relies on water during hot, dry summers,” he explained.
Narelle van der Wel, WMO’s Head of Cryosphere Monitoring, Predictions and Services, stressed that while some further glacier loss is unavoidable, the eventual scale of the decline is not predetermined.
“Some glacier loss is inevitable, but total loss of glaciers is not yet inevitable,” she said, pointing to emissions reductions as central to limiting future losses.
Preparing for moving baselines
The report does not attribute every observed change to climate change alone. WMO says pressure on water resources and natural variability also contribute.
Mr. Jenkinson said governments need to prepare for “moving baselines” as historical patterns become less reliable.
“The situation 30 years ago is not where we are today,” he said. Countries, he added, need to prepare “for those changes that have really already arrived”.
