Half a million people reportedly have been streaming out of a major Iraqi city that was seized by Islamist militants this week. The extremist group known as the Islamic State of Iraq and Syria, which has ties to al-Qaida, took over much of Mosul after Iraqi security forces seemingly abandoned their posts.
This morning, hundreds of people were filing past checkpoints on the road from Mosul to reach northern Iraq — a sight witnessed by NPR's Alice Fordham, who reported on the takeover for Morning Edition.
While ISIS has previously taken over smaller territories and towns in Iraq, Mosul is a hub of commercial activity and has a population of about 2 million. It was a hotly contested city during the U.S.-led invasion of Iraq.
"This is a really key strategic city," Fordham says, "and I don't think anyone was expecting it to fall so fast, so completely."
There are reports that the ISIS fighters might now be heading toward Baghdad. The group might also gain control of a crucial oil refinery.
A report by the International Organization for Migration says an estimated 500,000 people have fled Mosul since hostilities began Saturday morning. The Iraqi Security Force troops left the city Monday.
Iraqi Prime Minister Nouri al-Maliki "has asked Parliament to declare a state of emergency," the BBC reports.
"This is a hugely symbolic victory for the most extreme, violent and sectarian terrorist group in the Arab world today," Bruce Riedel of the Brookings Institution tells NPR's Deborah Amos.
Riedel says the takeover raises big questions about the U.S.-trained Iraqi military and that any response isn't as straightforward as building infrastructure or training soldiers.
"It's not a question of giving them airplanes or Humvees," he says. "It's a question of building a political state to which they feel some kind of loyalty. America can provide Humvees. America can't build a state for them."
Noting that Mosul is Iraq's third-largest city, the Christian Science Monitor reports that "the scale of the catastrophe, as troops loyal to Mr. Maliki flood north and troops controlled by the Kurdish Regional Government rush west and south, can't be overstated. Chicago is the United States' third-largest city. Munich is Germany's. Osaka is Japan's."
The figure of 500,000 people displaced in Mosul eclipses the 480,000 people that the U.N. recently estimated had fled Iraq's Anbar province in the first six months of this year.
