A quarter of a century after the Al-Qaeda attacks on the United States, jihadist groups still pose a major threat to security in Europe, but a new menace has surfaced that is driven mostly by young people online and the authorities are worried.

The exact size of the network behind what is being called nihilistic violent extremism is unclear. But police investigators from nine European countries found about 4,340 URL web addresses linked to "The COM," as the online community has become known, during a campaign to disrupt it in June and July.

Iceland's foreign ministry said Tuesday it had summoned the US ambassador after President Donald Trump posted a map that seemingly showed the island as part of the United States.

"Minister for Foreign Affairs, Thorgerdur Katrin Gunnarsdottir, summoned the U.S. Ambassador yesterday to convey a clear message that the image was wholly inappropriate," the ministry said in a statement to AFP, after Trump on Monday posted an image to social media with a map of North America in which countries like Canada, Greenland, Mexico, as well as Iceland were colored in with the U.S. flag.

Russia and North Korea opened the first road bridge across their narrow stretch of border Monday, creating a new physical link between the two countries as they expand cooperation.

North Korea only shares a 17-kilometer (10.5-mile) border with Russia, a tiny part of its porous northern border that stretches more than 1,400 kilometers (870 miles) and is mostly shared with China. But Pyongyang and Moscow have hailed the bridge's opening as yet another key moment in their booming ties.

Two people were killed and at least 10 injured after Russia struck the Ukrainian capital Kyiv with drones and missiles overnight on Tuesday, local authorities said.

The attack comes after a pause over the weekend as U.S. envoys Jared Kushner and Steve Witkoff arrived in Kyiv for their first official visit in a renewed push to end the war between Russia and Ukraine.

Iran's foreign ministry on Monday warned South Korea against military deployment or involvement in U.S. operations in the Strait of Hormuz, saying such a move would have "serious consequences".

Iran's top negotiator on Sunday threatened a more forceful response to any further U.S. attacks after Tehran targeted American warships in their latest round of clashes.

American envoys discussed "substantive plans" for next steps to end the Ukraine war during their meeting with Russian President Vladimir Putin, the White House said, before they headed to Kyiv on Sunday.

Iran said Sunday that its forces attacked a U.S. naval drone trying to enter the Strait of Hormuz, hours after targeting ships in retaliation for American strikes on three oil tankers.

President Donald Trump said that the Iran war was "small potatoes" for the United States, in his administration's latest bid to play down the conflict ahead of crucial midterm elections.

U.S. President Donald Trump said Friday he is sending envoys Steve Witkoff and Jared Kushner to Moscow and Kyiv with a plan to end more than four years of war in Ukraine.
