France and Italy bolstered border controls on Saturday after about 60,000 people crossed into Spain's enclave in North Africa, sparking one of the largest migrant crises for the European Union in recent years.

Iran's military accused the United States of "escalating tensions" in the Middle East on Saturday and warned countries in the region against cooperating with Washington during the ongoing conflict.

U.S. President Donald Trump has threatened to hit Iran "very hard," as U.S. media reported he was considering renewed heavy attacks as soon as this weekend, including against energy infrastructure targets.

After more than five months of war, which began on February 28 when the United States and Israel launched strikes on Iran, there is seemingly no end to the conflict, with resumed tit-for-tat attacks.

U.S. President Donald Trump said Friday the "terrible" migrant crisis facing Spain in its territory of Ceuta is what the United States will face if the opposition Democratic Party wins elections.

"It's terrible. Remember that picture. That's going to be us in three years if the wrong side gets in," he was quoted as saying by Fox News. "If the Democrats get in, you will not live a very good life."

The Polish foreign ministry summoned the Russian ambassador following the incursion of a missile into one of its eastern regions a day earlier, Prime Minister Donald Tusk said Friday.

"Today, the Polish Foreign Ministry summoned the Russian ambassador in connection with the missile that hit Polish territory yesterday," he wrote on X, after the missile left a crater in a field some 80 kilometers (50 miles) from Poland's border with Ukraine.

The United States and 10 Asian and European allies issued an alert Friday, warning companies against employing North Korean IT workers whose labor was generating crucial foreign currency to fund Pyongyang’s nuclear weapons program.

At least eighteen migrants have died trying to reach the Spanish exclave of Ceuta, where Spain deployed its military after thousands of people breached the border with Morocco and poured into the tiny Spanish territory.

Spanish Prime Minister Pedro Sánchez is expected to join Interior Minister Fernando Grande-Marlaska in a visit to Ceuta on Friday morning.

Most Americans say the war in Iran has not been worth fighting, and President Donald Trump's approval rating on Iran has fallen slightly since last month, according to a new AP-NORC poll.

The results are a stark repudiation of Trump's approach to the conflict, which has dragged on far longer than he originally predicted.

Russian attacks across Ukraine overnight into Thursday killed at least eight people and wounded dozens of others, officials said, with the heaviest casualties and aftermath reported in the eastern Dnipropetrovsk and western Lviv regions.

The attacks were the latest in a series of large-scale Russian strikes on Ukrainian cities that Russia has intensified over the summer, now occurring on a nearly weekly basis.

Ukrainian forces hit two of Russia's biggest oil refineries overnight in its latest long-range strikes, officials said, as Kyiv deepened its economic, military and diplomatic pressure on Moscow.

Ukraine's almost daily long-range drone and missile strikes using domestically developed weapons have battered Russian oil facilities for months. The operation has brought a fuel crisis that is embarrassing the Kremlin more than four years after Russia's all-out invasion of its neighbor.
