Authorities speculated that he was apart of at least 30 Norwegian Islamists volunteering in the war.

The British first instituted summer time in Egypt, during the Second World War, specifically between 1940 and 1945.
The practice was stopped after the war, but resumed 12 years later, in 1957.
Egypt normally observed summer time between the last Thursday in April and the last Thursday in September when the clocks were three hours ahead of Greenwich Mean Time (UTC+3).
The change was at midnight (local time); i.e.
on the last Thursday of April, one second after 23:59:59 became 1:00:00 on Friday.
Summer time ended on the last Thursday of September; on that Thursday, one second after 23:59:59 became 23:00:00.
The date did not change when the first 00:00 midnight occurred; for all practical purposes, midnight did not occur until after the "second" 23:59:59.
An exception was made for Ramadan; in 2006 the end of summer time took place one week earlier, on September 21, 2006, which took place before the start of the holy month of Ramadan.
The same practice recurred in 2007 and 2008, to avoid having longer days in Ramadan.
In 2009, summer time ended on Thursday, August 20, 5 weeks before the nominal end on the last Thursday in September.
In 2010, the summer time started on April 30, and ended on October 1, but between August 6 and September 10, DST was cancelled because of Ramadan.

On December 4, 1777, word reached Benjamin Franklin at Versailles that Philadelphia had fallen and that Burgoyne had surrendered.
Two days later, King Louis XVI assented to negotiations for an alliance.
The treaty was signed on February 6, 1778, and France declared war on Britain one month later, with hostilities beginning with naval skirmishes off Ushant in June.
Spain did not enter into the war until 1779, when it entered the war as an ally of France pursuant to the secret Treaty of Aranjuez.
Vergennes' diplomatic moves following the French entry into the war also had material impact on the later entry of the Dutch Republic into the war, and declarations of neutrality on the part of other important geopolitical players like Russia.
The British government of Lord North came under sharp criticism when the news of Burgoyne's surrender reached London.
Of Lord Germain it was said that "the secretary is incapable of conducting a war", and Horace Walpole opined (incorrectly, as it turned out) that "we are ... very near the end of the American war."
Lord North issued a proposal for peace terms in Parliament that did not include independence; when these were finally delivered to Congress by the Carlisle Peace Commission they were rejected. 
Ogaden War.
The Ogaden War (13 July 1977 – 15 March 1978) was a conflict fought between the Ethiopian government and Somali government.
The Djibouti government supported Somalia with military intelligence.
In a notable illustration of the nature of Cold War alliances, the Soviet Union switched from supplying aid to Somalia to supporting Ethiopia, which had previously been backed by the United States.
According to Ethiopian sources, the invaders numbered 70,000 troops, 40 fighter planes, 250 tanks, 350 armoured personnel carriers, and 600 artillery.
By the end of the month 60% of the Ogaden had been taken by the SNA-WSLF force, including Gode, which was captured by units commanded by Colonel Abdullahi Ahmed Irro.
The attacking forces did suffer some early setbacks; Ethiopian defenders at Dire Dawa and Jijiga inflicted heavy casualties on assaulting forces.
This in turn prompted the U.S. to later start supporting Somalia.
The war ended when Somali forces retreated back across the border and a truce was declared.
