Afghanistan's warring factions
Taleban forces dig in as they head for opposition territory
Since 1992 and the fall of Soviet-backed President Najibullah, seven groups have been battling to take control of Afghanistan.
Now it appears one of them may be near to victory - the radical Islamic students of the Taleban who now control around 90% of the country.
But who are the forces ranged against the Taleban and is there really any united opposition to the Taleban militia?
The so-called Northern Alliance of anti-Taleban groups are a disparate and divided force. Their opposition to the Taleban control is based on ethnic, cultural and religious differences. But political intrigue and personal grudges between the opposition commanders has often meant they have proved more effective when fighting alone than as an alliance.
Shortly after, General Malik turned his guns once more trapping many Taleban fighters who were killed or imprisoned.
Months later he was forced to retreat from Mazar-e-Sharif leaving the city for General Dostum to return.
The question of ethnicity
Opinions vary as to the importance of ethnicty in opposition to the Taleban, but some observers say that the recent conflicts have accentuated racial and religious differences amongst Afghans.
Indeed, almost all the Afghan militias have powerful overseas backers with Russia, the Central Asian republics, Pakistan and Saudi Arabia also known to have given their backing to one group or other.
Even if the Taleban do conquer most or all of northern Afghanistan, they will find it difficult to rule there. The mostly Pashtun Taleban are not popular in many areas of the north, where the inhabitants are ethnic Uzbeks and Tajiks.
Dostum and the Uzbecks
His opposition to the radical brand of Islam practiced by the Taleban is matched by their denunciation of his more relaxed approach to secular activities.
It is General Dostum's forces who initially received the full force of the Taleban's recent advances, including the fall of his headquarters at Mazar-e-Sharif.
Massoud's Tajik forces
From his time organising the resistance to the Russian military invasion, he is widely regarded as a politically skillful and experienced miliary tactician. But he remains in essence a warlord and does not make an easy or stable ally.
Now, it seems, Commander Massoud's forces are preparing to defend his Panjshir valley stronghold in the north-west of the country.
According to one report, radio broadcasts have been calling on elderly people, women and children to leave valley to avoid a possible blockade. The commander may be anxious that they may not be enough supplies to sustain civilians if fighting goes into the winter.
At the moment, the opposition's prospects look bleak. A lot may depend on whether they can, for once, unite against their common enemy and reopen some of their vital supply lines.
As for the Taleban, they will be hoping that their more cautious military strategy during their latest offensive will mean that they can hold on to Mazar-e-Sharif and go on to take the whole country.
But they have celebrated victories in the past, only to see them reversed.
During their previous occupation of Mazar-e Sharif last year, a turning point came when ethnic Hazaras rebelled against house to house searches being carried out by the Taleban. Some reports from the city suggest that such searches may be starting again.
