DUBLIN — Inside a large room in Facebook’s European headquarters in Ireland’s capital, about 40 employees sit at rows of desks, many with two computer screens and a sign representing a country in the European Union.

Large screens at the front display charts and other information about trends on the social network’s services, including Instagram and the messaging app WhatsApp. In the back, muted televisions broadcast BBC and other European news stations.

The cramped space is home to Facebook’s newly opened operations center to oversee the European Union’s parliamentary election, which will be held May 23 to May 26 in 28 countries.

Modeled after the “war room” that the Silicon Valley company created before last year’s midterm elections in the United States, the people inside are tasked with washing Facebook of misinformation, fake accounts and foreign meddling that could sway European voters. A similar command post was set up in Singapore for elections in India.
