Germany's Merkel urges European border reform after terrorist attacks

German Chancellor Angela Merkel said it was urgently necessary for Europe to reform the open-border Schengen area in light of recent terrorist attacks. "I want to mention the entry-exit system in the Schengen area, which should be ready in 2022," she said after a meeting with other European leaders on Tuesday.

"It is vitally necessary to know who comes in and who leaves the Schengen area."
