Afghanistan Unrest : Fighting Rages As Taliban Besiege Three Key Cities

Fighting is raging around three major cities in Southern and Western Afghanistan as Taliban militants seek to seize them from government forces.

Taliban fighters have entered parts of Herat, Lashkar Gah and Kandahar.

They have made rapid gains in rural areas since it was announced almost all foreign troops would go by September.

But the fate of these key cities could be crucial amid fears of a humanitarian crisis and how long government forces will be able to hold out.

The Taliban have already thought to have captured up to half of all Afghanistan's Territory.

Violence has surged across Afghanistan since early may, when the Taliban launched a sweeping offensive as US-led foreign forces began a final withdrawal that is now almost complete.
