RIYADH, Saudi Arabia — Islamist rebels in Syria shot down a government fighter jet and captured its pilot in the country’s north on Tuesday, anti-government activists said.

Videos posted online showed what appeared to be a jet catching fire and smashing into the ground, as well as rebels surrounding and insulting the pilot, who had parachuted safely to the ground.

An activist in one video from the site said the pilot was now a prisoner of the Nusra Front, Al Qaeda’s affiliate in Syria.

Syrian state news media said that the jet had been brought down by a surface-to-air missile, but said nothing of the fate of the pilot.
