Gunfire and explosions were heard Sunday as Libyan rebels entered the Libyan capital of Tripoli — a day after making significant gains in their war against leader Muammar Gaddafi.

According to Al Jazeera, thousands of people flooded into Green Sqaure at the heart of the city to celebrate what they hoped to be the end of Libyan leader Moammar Gaddafi’s four-decade-long rule.

In the rebel capital of Benghazi, huge crowds also gathered in celebration.  

On Sunday night, rebel leaders said that Gaddafi’s compound was surrounded, that his son Saif al-Islam had been captured and that his presidential guard had surrendered.

These are just of few of the images of the rebel forces as they pushed into Tripoli and the ensuing celebrations following their arrival.
