Trump warns Iran against nuclear weapon, criticizes Israel's Lebanon offensive

What happened

Al Jazeera Lebanon reports US President Donald Trump has issued a stern warning to Iran, stating “all hell will rain down” if Tehran tries to acquire a nuclear weapon. Speaking on the sidelines of a G7 summit in France, Trump described a pending US-Iran memorandum of understanding aimed at preventing Iran’s nuclear armament as a critical barrier, to be formally signed soon in Geneva, after which formal negotiations will proceed.

Outside Brief is treating this as a source-led account. Any disputed responsibility, casualty figure, battlefield claim or single-source assertion should be treated as unconfirmed/hearsay unless confirmed by another reliable source or a named official. Trump also made notably critical remarks about Israel’s ongoing military offensive in Lebanon. He expressed frustration over Israeli attacks on Beirut, which threatened to disrupt sensitive negotiations with Iran. Trump publicly called on Israeli Prime Minister Benjamin Netanyahu to act with greater responsibility in Lebanon, noting the high civilian toll and the destruction of apartment buildings during Israeli operations targeting Hezbollah.

The US president said Israel has been engaged in fighting Hezbollah for a long time with heavy casualties and questioned Israel's military approach, suggesting Syria might be more effective in dealing with Hezbollah. While affirming good relations with Netanyahu, Trump described Israel’s actions in Lebanon as excessive, underscoring civilian impacts amid the fighting.
