The BBC's Middle East correspondent Hugo Bachega joins paramedics on duty in Nabatieh, Lebanon - a city that was once vibrant, but is now abandoned.
In Lebanon, one in five people have been forced to leave their homes since fighting renewed in March.
At one ruined ambulance station, a paramedic shows where a colleague was killed by an Israeli strike while he was talking on the phone to his wife.
Israel says some ambulances and health facilities in Lebanon are being used by Hezbollah - but paramedics say there is no evidence of this claim.
Elsewhere, the Israel Defense Forces (IDF) said troops had killed more than 20 Hezbollah fighters operating from a hospital compound in Bint Jbeil on Sunday, the site of fierce fighting during the 2006 war between Israel and Hezbollah.
Lebanon's health ministry denied the claim, accusing Israel of targeting civilians and medical facilities.
