WASHINGTON (Sputnik) — At least 12 people were killed and 49 others injured when a truck drove into a Christmas Market at Breitscheidplatz in Berlin on Monday evening.
"Embassy Berlin encourages all US citizens to maintain good situational awareness, a low profile, and exercise vigilance," the message stated on Tuesday. "German media reports the Christmas Market attack investigation continues and the perpetrator of the attack may still be at large."
Earlier on Tuesday, US State Department spokesman John Kirby said he is not aware of any Americans injured or killed in the attack.
A 23-year-old Pakistani man, arrested after the attack has been released because prosecutors did not have evidence proving his links to the attack, according to media reports.
