One British soldier was killed and five others were injured in a roadside blast outside a former Taliban town in southern Afghanistan, officials said Monday.

The British Ministry of Defence said the five soldiers were airlifted to NATO bases for medical treatment and are expected to survive.

The incident occurred on Sunday in an area northeast of Musa Qala, a town located in northern Helmand province, when the soldiers were travelling in a NATO patrol vehicle.

Musa Qala had been a Taliban stronghold for 10 months until coalition forces recaptured it last month.

On Saturday, five civilians were killed and three others wounded when the taxi they were riding in struck a roadside bomb in southern Afghanistan.

The explosion occurred in the Panjwaii district of Kandahar province, where NATO troops and Taliban fighters have engaged in a number of several battles over the last 18 months.

Panjwaii district chief Shah Baran said such improvised explosive devices (IEDs) are often aimed at Afghan and NATO forces, "but this time it exploded on civilians."

Canada has about 2,500 troops operating in Kandahar province, one of the most violent regions in the country.

Seventy-seven of them have died since 2002, along with a Canadian diplomat.

Most of the deaths have been the result of IED attacks.

Trooper Richard Renaud was killed last Tuesday, when a roadside bomb struck his light-armoured vehicle while he was on reconnaissance north of Kandahar.

Since October 2001, a total of 87 British forces personnel have been killed in Afghanistan.
