Zarqa (Arabic الزرقاء az-Zarqā, local dialects ez-Zergā or ez-Zer'a, "The Blue One") is a city in Jordan located in the northwest of Amman. It has 399,000 inhabitants (1998). Zarqa is the capital of Zarqa Governorate (Arabic Muhāfazat az-Zarqā).
Zarqa is Jordan's industrial center, with 50% of the country's industry located in the city. This is the result of inexpensive real estate and the city's closeness to Amman.
Zarqa became known outside Jordan when, on September 6, 1970, the Popular Front for the Liberation of Palestine (PFLP) hijacked four passenger aircraft from Pan Am, TWA and Swissair on flights to New York from Brussels, Frankfurt and Zurich; and on September 9, 1970, hijacked a BOAC flight from Bombay to Rome.
The TWA, Swissair and BOAC flights, and their 400 passengers, were diverted to what became known as Dawson's Field in Zarqa. The passengers were released and the aircraft were subsequently blown up by the PFLP on September 12.
In response, King Hussein of Jordan formed a military government on September 16, 1970 and began shelling Palestinian guerrilla positions, eventually expelling the PLO from Jordan in what became known as Black September.
Today, Zarqa is also known as the birthplace and namesake of Abu Musab al-Zarqawi, leader of the Tawhid and Jihad terrorist group, which, in November 2004, announced it had changed its name to al-Qaeda in Iraq.
