People have staged a demonstration in Washington to protest against the United Sates’ use of assassination drones.

The protesters gathered outside the White House as they were chanting slogans and holding signs against Washington’s use of drones.

Saturday’s protest is part of a series of public protests, dubbed April Days of Action, which the organizers say will spread nationwide and target the infrastructure -- the military bases, universities and companies -- that supports the US government's overseas drone program.

The activists want President Barack Obama to abandon his assassination drone program.

US officials refuse to publicly discuss any details of the covert program and the death toll from drone strikes remains a mystery.

According to the London-based Bureau of Investigative Journalism, in Pakistan alone 366 strikes have killed up to 3,581 people, with 884 being innocent civilians.

Washington uses assassination drones in several countries, claiming that they target “terrorists.” According to witnesses, however, the attacks have mostly led to massive civilian casualties.
