The head of UN peacekeepers in the Democratic Republic of Congo says a new strategy is needed to prevent massacres² by the Lord's Resistance Army (LRA).

联合国驻刚果民主共和国维和部队首长称，必须采用新手段防止圣主抵抗军的屠杀。

Alan Doss spoke³ to the BBC after evidence emerged of a five day-rampage（暴跳，乱闹） by the rebel group last December in which more than 300 people died.

He said greater air mobility⁴ and better intelligence gathering⁵ was needed.

But Mr Doss said the LRA operated in small, highly mobile groups over a wide area, making the UN's job difficult.

The massacre was one of the worst ever committed by the group, Human Rights Watch said.

"We have to look at this as a problem dealing⁶ with small groups that move around a great deal," said Mr Doss.

"This requires better intelligence gathering, it requires particularly air mobility, and of course co-operation with the local people."

He added: "It didn't just happen in one place because... the LRA moves around a lot and these are small units, but of course they can inflict⁷（使承受，使遭受） terrible damage.

"But even small groups, moving as they do in the bush, can create havoc⁸（破坏，蹂躏） . Their best weapon is fear and they create fear by their extremely brutal⁹ and violent tactics（战术，策略） which we saw again in this latest massacre near Tapili."

LRA leaders initially¹⁰ claimed to be fighting to install a theocracy¹¹（神权政体） in Uganda based on the Biblical Ten Commandments.

But they now roam（漫游，流浪） across Sudan and Central African Republic, as well as DR Congo.

In the latest attack, rebels hacked¹² to death villagers and made others carry looted（抢劫，洗劫） goods. Some 250 people were abducted¹³（诱拐，绑架） .

The UN said it had heard rumours¹⁴ that an attack was to be launched around Christmas, and reinforced its troops in the area.

But they were deployed¹⁵ to towns like Dungu and Niangara rather than the remote villages where the killings¹⁶ took place.

On 13 December, a contingent¹⁷（分遣队） of LRA rebels crossed the Uele river and arrived at a market in the village of Mabanga Ya Talo.

They pretended to be Congolese soldiers and asked for food and other goods.

They then asked people to carry the goods back to where they had crossed the river, and when the villagers refused, the rebels turned on them.

Adults were attacked, captured, imprisoned¹⁹ in huts, then taken out and made to act as porters.

Anyone unable to keep up with the forced march was brutally killed.

The acts were repeated in villages all the way to Tapili, about 45km (30 miles) away.

Human Rights Watch, working with local organisations, has verified 321 deaths - but other activists²⁰ have given far higher estimates.

Witnesses say the stench（恶臭，臭气） of death hung over the area for weeks.

Children were a particular target of the LRA.

At least 80 were taken by force - boys to become fighters, girls to be used as sex slaves by LRA fighters.
