Two British and one American soldier are among at least 23 people to have been killed in the latest spate of bomb attacks in Afghanistan.
Most of the latest victims died in a suicide blast in the eastern city of Jalalabad. Witnesses say the bomber rammed his vehicle into a US convoy as it drove through a busy market. Ten civilians and a soldier died.
The two British soldiers were killed in the southern province of Helmand. They were on patrol when their vehicle was hit by a roadside bomb.
A further ten people are reported to have lost their lives in suicide attacks elsewhere in Helmand and Kandahar province yesterday.
The deteriorating security situation in Afghanistan was top of the agenda as President Hamid Karzai met British Prime Minister Gordon Brown in London.
The country is going through its worst period of violence since the overthrow of the Taliban in 2001.
