Officials Confirm Two New Yorkers Were Killed In The Brussels Attacks

Two New Yorkers, siblings Sascha and Alexander Pinczowski, died in the attacks at the Brussels airport on Tuesday.

The Dutch siblings were waiting at the Delta Air Lines counter to check in for their flight to New York, according to CNN. Alexander was apparently on the phone with their parents when the attacks started, and the phone call cut off.

At least 31 people died and 300 people were wounded in the attacks on Tuesday, which hit the international airport and a subway station. A French and a Chinese citizen also died in the attacks.

In a statement, the Pinczowski siblings' family said,

We received confirmation this morning from Belgian Authorities and the Dutch Embassy of the positive identification of the remains of Alexander and Sascha... We are grateful to have closure on this tragic situation, and are thankful for the thoughts and prayers from all. The family is in the process of making arrangements.

An American couple is still missing after the attack, according to NBC. Justin and Stephanie Shults live in Belgium and were dropping off Stephanie's mother at the airport when the blasts went off. They have not been located since the attack.

In a statement, Secretary of State John Kerry claimed Americans died in the attacks, though it is not clear to whom he was referring. In Belgium on Friday, Kerry said,

United States is praying and grieving with you for the loved ones of those cruelly taken from us, including Americans, and for the many who were injured in these despicable attacks.
