An Israeli drone strike in central Syria killed two fighters from Lebanon's Hezbollah movement on Saturday, a war monitor said.

"An Israeli drone fired two missiles at a Hezbollah car and truck near the town of Qusayr in Homs province, as they were on their way to al-Dabaa military airport, killing at least two Hezbollah fighters and wounding others," said the Syrian Observatory for Human Rights.

Hezbollah has yet to announce any casualties among its ranks today.
