Syria's opposition coalition early Tuesday elected a little-known American-educated IT manager and Islamic activist to head an interim government to administer the areas seized by rebel forces from the forces of President Bashar al-Assad.

Ghassan Hitto received 35 votes out of 48 ballots cast by the opposition Syrian National Coalition's 63 active members during a meeting in Istanbul. The results were read aloud by coalition member Hisham Marwa to applause from a few dozen of his colleagues who had waited until after 1 a.m. to hear the results.

"I miss my wife and children and I look forward to seeing them soon," said Hitto, who has lived in the United States for decades and recently moved from Texas to Turkey to help co-ordinate aid to rebel-held areas.

When asked what his interim government's first priority would be, Hitto said he planned to give a speech later Tuesday outlining his plans.

Hopes that rebels will unite against Assad

Coalition members hope the new government will unite the rebels fighting Assad's forces on the ground and provide services to Syrians living in rebel-held areas, many of which have been battered by the country's civil war and suffer acute shortages of food, electricity and medical services.

But the new government faces huge challenges, starting with its ability to gain recognition from rebel factions on the ground.

As rebels have progressed in northern and eastern Syria, a patchwork of rebel groups and local councils have sought to fill the void left by the government's withdrawal by organizing security patrols, reopening bakeries and running courts and prisons. It is unclear if these groups, many of which have taken charge of their own towns, will accept an outside authority, especially if it is headed by someone who has spent decades abroad.

"How can a civilian come and tell these fighters on the ground, 'Drop your weapons. It's my turn to rule'?" asked Adib Shishakly, the coalition's representative to a group of Gulf nations known as the Gulf Cooperation Council, before the results were announced.

Hitto's election follows two failed attempts to form interim governments due to opposition infighting. Coalition members also say they received insufficient international support to allow them to project their authority to groups inside Syria. The new government could have the same problem.

"You have to find a way to co-operate with these groups and you can only rule by providing services, which requires funding," Shishakly said.

The council's creation of an interim government renders even more remote the chances of ending the war through negotiations with Assad's government — the preferred solution of the U.S. and other world powers.

U.S. supports peace plan

The U.S. has been cool to the idea of a rebel government to rival Assad's and supports a peace plan put forward by the UN and the Arab League that calls for the formation of a transitional government that represents the regime and the opposition.

UN Secretary-General Ban Ki-moon on Tuesday reiterated his call for a political solution "while there is still time to prevent Syria's complete destruction."

On Monday, U.S. Secretary of State John Kerry also said the Obama administration wants to leave the door open for a political solution. Regarding the rebels, he also said the U.S. would not "stand in the way of other countries that made a decision to provide arms, whether it's France or Britain or others."

French President Francois Hollande said last week that his country and Britain were pushing the European Union to lift its arms embargo on Syria so they can arm the rebels. Germany and other EU nations oppose the move, saying it will exacerbate the violence.

Coalition members in Istanbul rejected the idea of negotiating with the Syrian government before Assad leaves power.

"We've heard a lot about this 'peaceful solution,' but there are no positive, real steps from the regime," said Nizar Al Hrakey, a coalition member.

On Monday, the head of Syria's largest official rebel group, the Free Syrian Army, threw his weight behind the idea of an interim government.

"We consider it the only legal government in the country," Gen. Salim Idris told reporters in Istanbul.

Idris's authority limited

However, Idris's authority within the country remains limited, with some of the most successful rebel groups on the ground rejecting his authority.

The Syrian government did not immediately comment on the Istanbul meeting. It blames the war on a foreign conspiracy to weaken Syria being carried out by terrorists on the ground.

Hitto did not receive a resounding mandate from the coalition, of which he is not a member. Of the group's 63 active members, only 48 voted. Four cast blank ballots and Hitto received 35 of the remaining votes.

Hitto was born in Damascus, the Syrian capital, in 1963, according to his official resume provided by the coalition. Little known in Syria, Hitto has lived in the United States for more than two decades, most recently in Texas. He has academic degrees from Purdue University in Indiana and Indiana Wesleyan University.

He worked for a number of different technology companies and helped run a Muslim private school called the Brighter Horizons Academy. He is also a founding member of the Muslim Legal Fund of America, which was founded to give legal aid to Muslims following the September 11, 2001, terrorist attacks.

Hitto married with children

He is married with four children.

Activist Ghassan Yassin, who watched the vote after travelling from the embattled city of Aleppo, said he saw "no reasons to be optimistic about the formation of an interim government."

He said he had only heard of Hitto recently and doubted his government would have the resources to make a difference.

"The question is not whether there is an interim government, but whether there will be any support for it," he said.

Syria's conflict began with political protests in March 2011, and has since spiraled into a civil war, with hundreds of rebel groups fighting Assad's forces across the country. The UN says more than 70,000 people have been killed and millions pushed from their homes by the violence.
