Kigali, Friday

SCORES of Rwanda Patriotic Front rebels strolled casually near the

government-held centre of Kigali during a civil war lull in the Rwandan

capital today, witnesses said.

The scene confirmed that the rebels have gained ground from the army

in heavy battles. But UN officials doubt that fighting and tribal

bloodshed will be checked by a Tanzanian mediated truce.

''The RPF definitely gained some ground,'' a witness said. ''We have

never seen them so close to the city centre. They appeared very

confident, with their weapons slung over their backs.''

UN officers said it was hard to say how far the rebels had advanced,

as their strategy was to hit from all sides. But government forces

appeared to be in disarray.

''The RPF appears to have high morale and their men are well trained

as street fighters,'' one officer said.

Aid workers said rebels had also surrounded the northwestern town of

Ruhengeri and were battling to capture it.

Abdul Kabia, director of UNAMIR, the UN Assistance Mission in Rwanda,

said battles with artillery, mortars and rockets raged across Kigali

until this morning's lull but he could not comment on who had the

advantage.

''The position is very fluid,'' said Kabia.

Some 300 refugees, mostly Tutsi, are trapped at the Hotel des Mille

Collines. Government troops, militiamen and a mob blocked their

evacuation aboard a UN convoy on Tuesday and slashed seven of them with

machetes.

Abdul Kabia said UNAMIR want to try again to move the refugees but had

made no progress with Rwandan army commanders.

A mortar bomb exploded near the terminal at Kigali airport, jointly

held by UN and government forces, and a Canadian transport plane was hit

by sniper fire. Rebels and government forces both denied firing.

UNAMIR closed the airport, the only reliable link for the 270-strong

force to the outside world. Abdul Kabia said he did not expect it to

reopen today as UNAMIR wanted letters from both sides promising it would

not be targeted.

In the Kenyan capital of Nairobi, the UN special envoy to Rwanda said

he doubted a Tanzanian announcement that both sides agreed separately to

stop fighting from tomorrow would end the civil war.

''I cannot be optimistic as 10 days ago we found ourselves in almost

the same situation with two unilateral ceasefire declarations and this

was not implemented on the ground,'' said UN Special Representative

Jacques-Roger Booh-Booh.

The RFP's representative in Brussels, James Rwego, said the RPF had

signed a ceasefire declaration that will come into effect at midnight on

Sunday.

He said RPF officials had signed the accord yesterday in the Zairean

town of Gbadolite. The Belgian news agency Belga, quoting Zaire's

ambassador in Brussels, said it believed the Rwanda armed forces had

signed the same deal today in Gbadolite.

However, a spokesman for the Zairean embassay said it was not clear

whether a delegation from the Rwandan armed forces had yet arrived in

Gbadolite to sign the document.
