<h1>Middle Eastern nations agree to ceasefire after 12-day conflict involving nuclear sites and US airstrikes</h1> A ceasefire between two Middle Eastern nations took effect after initial violations by both sides. The conflict began when one country targeted the other's nuclear and military sites, citing security concerns about atomic weapons development. The 12-day war expanded when the US joined with airstrikes, prompting limited retaliation against a US base. The American president expressed frustration with both parties for ceasefire violations but later confirmed the truce held after diplomatic intervention. The conflict resulted in hundreds of casualties, with at least 28 deaths in one country and nearly 1,000 in the other.
