Fierce fighting has been taking place for a twelfth day in and around the town of Al Quseir in Syria. Rebels hold it at the moment but they are under constant bombardment from Government forces.
Both sides want to hold it.
For the Government the town connects Damascus with the Mediterranean. For the rebels it's a key point in the supply line between Lebanon and the key city of Homs, the third biggest in the country.
Dozens have died there already.
It's the first battle involving dozens of fighters from the Lebanese group Hezbollah, which is fighting on the side of President Assad.
We have been speaking by phone with a few people inside Al Quseir.
Here's what they say.
The first witness is Abu Al Huda Al Homsi. He is part of the rebel Co-ordinating Committee.
A doctor in the town explains the problems they face. He says "we are at war with Hezbollah".
Another doctor says his last oxygen bottle is now gone. He says they have appealed to everyone, to the Red Cross and the Red Crescent but he claims no one is interested.
The battle won't be over soon. Both sides are dug in. More casualties are inevitable. The fighting there was even on the lips of the Syrian Opposition as they rejected calls to join a peace conference, slated for Geneva next month. The slaughter in Quseir, they claimed, made the idea of negotiating with President Asad's men impossible.
