In Afghanistan, fighting between government forces and Taliban continues around three major cities in south-western parts of the country.
Taliban fighters have entered parts of Herat, Lashkar Gah and Kandahar.
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.
In Lashkar Gah, Taliban had been pushed back by nightfall.
The commander of Afghan forces said they had inflicted significant casualties on Taliban.
Thousands have been displaced in Kandahar amid fighting between the army and the Taliban.
