BEIRUT — Hundreds of Syrians, including four wounded people, crossed into Lebanon on Saturday fleeing violence in their country as an uprising against President Bashar Assad’s regime entered its eighth week, Lebanese security officials said.

The officials said cracks of gunfire coming from the western Syrian town of Talkalakh could be heard on the Lebanese side of the border since morning hours. More than 5,000 Syrians have fled the area in the past weeks, with more than 500 people crossing the border on Saturday, the officials said.

The shooting in Talkalakh comes a day after Syrian security forces opened fire on thousands of protesters at different rallies across the country, killing at least six people.

Human rights groups say more than 775 people have been killed since the start of the protest movement in Syria in mid-March.

The Lebanese officials said the wounded who crossed the border Saturday included a 26-year-old man who suffered a gunshot in his back and two women, also with bullet wounds. The fourth, a 30-year-old man, died of his wounds later at a north Lebanon hospital.

On Friday, rallies had spread to new areas of the Syrian capital Damascus, suggesting opposition to the 40-year Assad dynasty remains unbowed despite one of the most violent crackdowns in the uprisings that have gripped the Arab world.

Assad has come under scathing criticism for his crackdown, with the United States and Europe imposing sanctions.
