At least three people have died and five have been wounded after a suicide bombing in a Lebanese town near the border with Syria, according to Reuters.
The blast happened in the small town of Nabi Osmane, a stronghold of the militant Hezbollah group, which has been fighting alongside forces loyal to Syrian President Bashar al-Assad.
Syrian soldiers entered eastern districts of the town of Yabroud and advanced towards the main street of the last major rebel bastion near the Lebanese border north of Damascus, Lebanese media reported.
According to Al Mayadeen television, capturing Yabroud would help President Bashar al-Assad secure the land route linking his Mediterranean coastal stronghold with the capital Damascus, and choke off a cross-border rebel supply line from Lebanon.
Mass street protests against Assad broke out three years ago and escalated into civil war after a violent security crackdown on demonstrators.
