Iran said it launched a missile attack on US-led forces in Iraq in the early hours of Wednesday in retaliation for the US drone strike on an Iranian commander whose killing has raised fears of a wider war in the Middle East. Secretary of State Mike Pompeo was asked Tuesday about claims that Iran was planning imminent attacks against Americans ahead of Qasem Soleimani's killing. American allies in Europe are watching carefully and also criticizing the US airstrike. And, should we prepare for cyberattacks from Iran? That's the message coming from the US government, which expects retaliation from Iran. Also, a knitted green sweater has become deeply symbolic to people working to remember the lessons of the Holocaust. The sweater, from an exhibit at the Holocaust Memorial Museum in Washington, DC, was knit for a girl named Krystyna Chiger by her grandmother. Chiger wore it the entire time she was in hiding in the sewers of Ukraine. To honor Chiger's story of survival, knitters have developed a pattern for the sweater and are encouraging others to create their own.
