The White House reportedly underwent a brief lockdown Sunday after a pair of balloons landed on the property.

There were balloons at the White House, but this was no party.

The White House underwent a brief lockdown Sunday when a pair of balloons drifted onto the property.

NBC News broke the news on Twitter, tweeting at 1:25 p.m. that the White House was on lockdown "for [an] unspecified reason." 

About 10 minutes later the outlet tweeted an "all clear" and cited "several 'party balloons'" for the freakout.

President Barack Obama was not home when the incident occurred but had just arrived in Vietnam.

The hot-air scare came two days after a shooting outside the White House complex left an armed man critically wounded by a uniformed Secret Service officer. Obama was at Andrews Air Force Base at the time of that incident.

Homeland Security and the Secret Service could not immediately be reached for comment on the balloon incident.
