Italian defeats prompted Germany to deploy an expeditionary force to North Africa. Operation Sonnenblaume (6 February - 25 May) was the name given to the dispatch of German troops to North Africa in February 1941, The Italian 10th Army had been destroyed by the British and Allied Western Desert Force attacks during Operation Compass (9 December 1940 – 9 February 1941). Sonnenblume succeeded because the ability of the Germans to mount an offensive was underestimated by General Archbald Wavell, the Commander in Chief Middle East, the War Office and by Winston Churchill.
In December 1940, British Empire forces began counter-offensives against Italian forces in Egypt and Italian East Africa. The offensives were highly successful. Operation Compass was the first large British military operation of the Western Desert Campaign (1940–1943) during the Second World War, and took place between 9 December 1940 to 9 February 1941.
The Siege of Tobruk lasted for 241 days in 1941, after Axis forces advanced through Cyrenaica from El Agheila in Operation Sonnenblume against Allied forces in Libya, during the Western Desert Campaign (1940–1943) of the Second World War. The siege diverted Axis troops from the frontier and the Tobruk garrison repulsed several Axis attacks.
Operation Brevity was a limited offensive conducted in mid-May 1941, during the Western Desert Campaign of the Second World War. Conceived by the commander-in-chief of the British Middle East Command, General Archibald Wavell, Brevity was intended to be a rapid blow against weak Axis front-line forces in the Sollum–Capuzzo–Bardia area of the border between Egypt and Libya. Although the operation got off to a promising start, throwing the Axis high command into confusion, most of its early gains were lost to local counter-attacks, and with German reinforcements being rushed to the front the operation was called off after one day.
The Battle of Gazala was fought during the Western Desert Campaign, west of the port of Tobruk in Libya, from 26 May to 21 June 1942. As both sides neared exhaustion, the Eighth Army checked the Axis advance at the First Battle of El Alamein. To support the Axis advance into Egypt, the planned attack on Malta (Operation Herkules) was postponed. The British were able to revive Malta as a base for attacks on Axis convoys to Libya, greatly complicating Axis supply difficulties at El Alamein.
In 1963, the Seven Sisters controlled 86% of the oil produced by OPEC countries, but by 1970 the rise of "independent oil companies" had decreased their share to 77%. The entry of three new oil producers—Algeria, Libya, and Nigeria—meant that by 1970, 81 oil companies were doing business in the Middle East.
Libya concludes five weeks of negotiations with Western oil companies in Tripoli on behalf of itself, Saudi Arabia, Algeria, and Iraq. The agreement raises posted prices of oil delivered to the Mediterranean from $2.55 to $3.45 per barrel; provides for a 2.5 percent annual price increase plus inflation allowance; raises the tax rate from a range of 50-58 percent to 60 percent of the posted price.
On March 16, 1998, Libya issued the first official Interpol arrest warrant against bin Laden and three other people. They were charged for killing Silvan Becker, agent of Germany's domestic intelligence service, the Federal Office for the Protection of the Constitution, in the Terrorism Department, and his wife Vera in Libya on March 10, 1994.
