Authorities in Germany have detained a man for questioning in connection to the deadly attack on a Christmas market in Berlin earlier this month.
Last week, police in Milan, Italy, shot and killed Anis Amri, the Tunisian man suspected of driving a truck into the market on Dec. 19. Twelve people died in that attack.
Now they are questioning a 40-year-old man whose phone number was found in Amri's cellphone.
"This new suspect is also from Tunisia and police say investigations indicate he may have been involved in the attack," Kerry Skyring reports for NPR.
