"The Israel Defense Forces warns residents of the Dahiyeh area in Beirut and calls on them to evacuate to preserve their safety.

However, both Israel and the US have stated that Israeli activities in Lebanon will remain separate from the ongoing conflict with Iran.Due to the presence of Iranian proxy groups in the region, Tehran continues to push for the inclusion of Lebanon and has warned of greater consequences for the US and Israel.As per Iran's Tasnim news, the Iranian negotiating team has stopped exchanging messages with the US through mediators due to Israel's bombardment in Lebanon.Along with the suspension of the talks, the news agency reported that Iran and its Resistance Front, which includes its allies in Yemen, Lebanon and Iraq, are now mulling ​an agenda to completely block the Strait of Hormuz and the Bab al-Mandab Strait in ⁠order to "punish" Israel and its supporters.Earlier on Monday, Iran's foreign minister, Abbas Araghchi, also called for the inclusion of Lebanon in the ceasefire, adding that if Iran were to respond, the US and Israel would be responsible for the consequences.Israel and Lebanon's conflict, renewed on March 2, as the US-Iran war spilt over into the region.

But don’t the Dumocrats, and various seemingly unpatriotic Republicans, understand that it is MUCH tougher for me to properly do my job and negotiate," he wrote, while targeting the Democrats and Republicans who have been critical of his war against Tehran.
