Riyadh: Regional power Saudi Arabia, which launched air strikes Thursday on Huthi rebels in Yemen, has intervened militarily in the region several times in the past.
THE SIX-DAY WAR
June 5-10, 1967
Riyadh announces that it has sent aircraft, armoured vehicles and large quantities of weapons and ammunition, as well as a detachment of paratroopers, to help Jordanian forces fight Israel.
THE YOM KIPPUR WAR
October 6-25, 1973
Between 1,000 and 2,000 Saudi soldiers based in Jordan since the Six-Day War fight alongside Syrians against Israel on the Golan Heights.
On October 16, Riyadh and other oil producers use the commodity as a weapon by steeply increasing the price of crude.
The Saudi troops remain deployed on the Golan Heights until withdrawing on October 4, 1976.
THE GULF WAR
January 17-February 28, 1991
Riyadh, a member of the international coalition to drive Iraq from Kuwait, which it invaded in August 1990, plays a key role in the Gulf war by putting its territory and military bases at the coalition`s disposal.

After Shiite rebels kill a Saudi border guard, Riyadh carries out a three-month-long intervention to stop them infiltrating. The Saudi authorities say the attacks are confined to its territory, while the rebels accuse it of bombarding Yemeni territory.
In January 2010, amid a ceasefire between the rebels and Sanaa, Saudi Arabia says 109 Saudi soldiers were killed during the operation, the biggest carried out by Riyadh since it took part in the Gulf War.
