Sept 19 (Reuters) - A British soldier has been killed and another has been injured in an explosion in southern Afghanistan's embattled Helmand province, the Ministry of Defence said on Tuesday.

The two were in a logistics convoy northeast of the town of Gereshk when the explosion happened on Monday afternoon.

More than 7,000 people have been killed during the past 19 months in Afghanistan, the bloodiest period since the resurgent Taliban's overthrow.

Here are the figures for foreign military deaths in Afghanistan since the Taliban government was toppled in 2001:
