INTERVIEW:Brahimi to firm up role, not urge Assad exit yet

* Brahimi taking over from Kofi Annan as mediator

* Says may go to New York as early as next week for talks

* Says too early to say if he will urge Assad to resign

BEIRUT, Aug 18 (Reuters) - The Algerian diplomat set to

become the new international mediator on Syria has said he

urgently needs to clarify what support the United Nations can

give him and said it is too early to say whether President

Bashar al-Assad should step down.

Lakhdar Brahimi, a veteran diplomat, was speaking a day

after the United Nations confirmed he would take over Kofi

Annan's mediation role. Annan, who steps down at the end of the

month with his peace plan in tatters, resigned complaining that

divisions within the Security Council had hampered his work.

Brahimi made it clear he was acutely aware of the Security

Council problem and would therefore need to urgently clarify

what support the United Nations can offer him to ensure his

mission has a better chance of success.

"When I go to New York I will be asking for lots of things.

How to organise ourselves, whom we are going to talk to, (and)

what kind of plan we are going to put together," he told Reuters

in a phone interview from Paris on Saturday.

"We will start discussing all this, what kind of support I

will get and what kind of support I will need to try and do this

job," he added.

Brahimi takes over the role - described as an "impossible

mission" by a senior French diplomat - at a time when fighting

between government forces and rebels is in full swing with no

sign of an imminent ceasefire.

More than 18,000 people have been killed and some 170,000

have so far fled the country, according to the United Nations.

Yet the Security Council remains deeply divided with Russia

and China vetoing sanctions on Assad, arguing that the West is

seeking to topple the Syrian government. The three other

permanent members of the Council - the United States, Britain

and France - all favour tough action however.

Brahimi said he would head to New York as early as next week

to officially accept his mission and will later go on to Cairo

to meet Arab League chief Nabil Elaraby.

He conceded that the problems Annan had faced had given him

pause for thought.

"I've been struggling with the very principle of getting on

such a mission and I've been discussing with the United Nations,

with the Secretary General of the United Nations, how they saw

this and how I would fit in," he said.

In a separate interview with France 24 television, Brahimi

said he would soon meet with the Security Council.

"We are going to discuss very seriously how they can help,"

he said. "They are asking me to do this job. If they don't

support me, there is no job. They are divided, but surely they

can unite on something like this and I hope they will."

Brahimi, 78, served as a U.N. special envoy in Iraq after

the U.S. invasion that toppled Saddam Hussein, in Afghanistan,

both before and after the end of Taliban rule, and in South

Africa as it emerged from the apartheid era.

"TOO EARLY" TO SAY WHETHER ASSAD SHOULD GO

Describing the situation in Syria as "absolutely terrible",

he said he would do his best to find a way of ending the

17-month-old conflict.

"The situation in Syria is dire, the situation is absolutely

terrible. You see that on your television screen everyday.

Villages and cities seem to be flattened from the bombing," he

said.

"I could not refuse in a situation like this where hundreds

and thousands, maybe millions of people are suffering to try and

help no matter how difficult the situation is."

However, he declined to be drawn on whether he thought

President Assad should step down - in contrast to Annan who said

it was clear the Syrian leader "must leave office".

"It's much too early for me to say. I don't know enough

about what is happening," Brahimi said, when asked whether he

would be asking Assad to resign.

He had not yet held any talks with Assad but said he would

meet him and the troubled country's opposition leaders as soon

as the time was right.

"That's another basic principle. Never refuse to talk to

anybody, and if for anything, for the understanding of the

situation."

Brahimi, a Nobel Peace laureate, will have a new title,

Joint Special Representative for Syria. Diplomats said the

change was to distance himself from Annan.

He said he'd been in contact with Annan, a former U.N.

Secretary-General, in recent months but declined to comment on

why Annan's mission failed or whether he'd been advised to avoid

undertaking certain initiatives.

"I've been in touch with him (Annan) throughout his

mediation and in fact I spoke to him only yesterday," he said.

"I can't comment on his (peace) plan but I can say that we

will try to solve this conflict, today is better than tomorrow."

The United Nations confirmed Brahimi was to become the next

mediator as U.N. observers in Syria prepared to withdraw due to

the violence.

Brahimi said he would draw on his past experience.

"Now we are talking about Syria. What I have seen elsewhere

will be useful to remember, maybe there will be ideas on how to

do a few things and ideas on how not to do things," he said.

"It is the Syrians who will make peace or war, nobody else

and we will be there to try to help them as much as they are

willing to accept our help."
