Survivors fleeing the Sudanese city of El-Fasher told AFP on Saturday that paramilitary fighters separated families and killed children in front of their parents, with tens of thousands still trapped following the city's fall.

Egypt officially opened on Saturday the Grand Egyptian Museum, a long-awaited, billion-dollar showcase of pharaonic grandeur that Cairo hopes will revive tourism and boost its battered economy.

Two machines resembling robotic vacuum cleaners sped around a ring colliding, shooting sparks and catching fire, as Iranian engineering students watched from behind plexiglass.

The dramatic clash was just one of many opportunities for competitors to go head-to-head at the country's Tech Olympics, to determine the future of its engineering talents.

Iran aspires to become a key regional player in emerging technologies, despite decades of international sanctions that have stifled its development.

Bangladesh's dock workers escalated a strike on Saturday at the country's biggest port, Chattogram, protesting plans by the interim government to lease operating licences to a foreign company.

"Foreign expert operators would increase the foreign investment and enhance the efficiency," Chattogram Port Authority chairman S. M. Moniruzzaman told AFP.
