Gordon Brown is to outline to the Commons the government's revised strategy for the war in Afghanistan, following his visit to the country.

The prime minister met Afghan President Hamid Karzai on Monday

He is expected to say Pakistan - which was also on his tour - must be part of a solution to Afghanistan's problems.

Mr Brown has spoken of a "chain of terror" linking the region to the UK.

The prime minister is unlikely to commit further UK soldiers to the war, other than those to provide security at the forthcoming（即将到来的） presidential election.

Mr Brown's statement comes just hours after a British soldier was killed in southern Afghanistan.

The soldier, who was serving with the 1st Battalion¹ Welsh Guards died on Tuesday in an explosion while on foot patrol near Gereshk in Helmand Province.

The soldier's name is expected to be released by the Ministry² of Defence on Wednesday.

International terrorism

The so-called "Af-Pak" solution is likely to echo US President Obama's new policy unveiled in March.

The BBC's international development correspondent David Loyn said the UK was also expected to back its latest thinking with £500m in aid.

Mr Brown will tell MPs that efforts to counter extremism must be concentrated on those areas where al-Qaeda and the Taleban（塔利班） operate with impunity³.

The prime minister has said that three-quarters of terrorist activity in Britain originates from the border area between Afghanistan and Pakistan.

During his trip to the two countries, Mr Brown said efforts to defeat international terrorism had to be made in Helmand Province and in neighbouring Pakistan.

"Our approach to these countries is different, but must be complementary," he said.
