Four Americans have gone missing in Brussels since it faced terror attacks by Daesh Takfiri militants.
The families and friends of the four took to social media to call out for help.
Early on Tuesday, three coordinated nail bombings rocked EU’s de facto capital leaving at least 34 people dead.
Two of the explosions ripped through the international departure hall of the airport in Zaventem, near the American Airlines check-in desk and another near a coffee shop.
An hour after the airport bombings, another bomb went off at Maelbeek metro station, 10 kilometers away.

In Brussels police are still desperately hunting a dangerous terrorist after he fled a triple-suicide bombing in the city that left 34 dead, as officials search for news on U.S. citizens who went missing during the attack and medics tend to nine more Americans lying wounded in hospital.
Meanwhile in Buenos Aires President Barack Obama was dancing the night away with wife Michelle at a glitzy state dinner alongside Argentine President Mauricio Macri and his first lady Juliana Awada as part of a two-day state visit.
Despite increasing calls from the likes of Donald Trump and Ted Cruz for the President to return home in the wake of the Brussels attack, Obama showed his determination to carry on regardless Wednesday night.
