At least 11 people have been killed in clashes over the last four days between two rival militias in northern Afghanistan.

The fighting between the forces of Abdul Rashid Dostum and Atta Mohammed comes even as British troops are preparing to set up a reconstruction project in the main city in the north, Mazar-e-Sharif.
Dostum's faction is fighting for control of the north
It is just the latest in a long line of battles between the two factions who have fought for control of the north since the Taleban was overthrown a year-and-a-half ago.
Dozens of people have been killed in clashes, yet the two warlords have been able to carry on fighting because an international peacekeeping force has only been established in Kabul.
Karzai's pleas 'unheard'
President Hamid Karzai has therefore been unable to assert his control beyond the capital, as provincial leaders - often with sizeable private armies - have fought each other or entrenched their positions in different parts of the country.
Central authority does not extend far beyond Kabul
This threatens to undermine reconstruction efforts in Afghanistan.
Mr Karzai's repeated requests for international peacekeepers to cover the whole of Afghanistan, not just Kabul, have been turned down.
Instead, joint military and civilian teams are being established in eight parts of the country.
About 50 British troops are preparing to set up one of the teams in Mazar-e-Sharif.
As well as taking part in reconstruction work, the team is supposed to help in the demobilisation of private militias.
Observers say the key to establishing order is disarming the different factions in Afghanistan, but they say this will only happen if more pressure is put on all parties involved.
