104 Hezbollah militants have died in the past few months, while fighting in Reef Dimashq and Reef Homs, Syria, a watchdog reported.
According to the Syrian Observatory for Human Rights, a British-based opposition-aligned organisation monitoring the conflict, 46 Hezbollah fighters have been killed in the last five days, during fierce fighting in Qusayr.
The watchdog reported that sources confirmed a further 20 Hezbollah members have been killed in battles around Qusayr this month, whilst the organisation lost a further 38 members during Autumn in Reef Qusayr and Reef Dimashq.
Hezbollah has been involved in the Syrian conflict for some time, with its fighters pouring into Syria to take part in the ongoing battle for Qusayr, a strategic town near the Lebanese border which links Damascus to Bashar al-Assad's coastal support base.
Hezbollah initially claimed that it would only get involved in the conflict to defend border villages, home to Lebanese Shi'ites, as well as holy Shi'ite shrines in Damascus.
Hezbollah denied any involvement in the Syrian conflict but the militia's involvement has been confirmed as a number of public funerals have taken place in recent days, for militants killed in the ongoing Qusayr fighting.
