A doctor and a 16-year-old have been killed in Sudan amid demonstrations against President Omar al-Bashir.

A member of the Sudan Doctors Syndicate said both were shot in the head by state forces who were firing directly on demonstrators.

Nine other demonstrators were reportedly wounded in the clashes as protesters staged a sit-in at a hospital in the capital Khartoum.

It marks the fifth week of anti-government protests.

The doctor who died, Dr Babiker Abdulhemeed, had “over 14 live bullets in his body”, he added.

Protesters had gathered outside the Royal Care International Hospital in the Burri district of the capital for a sit-in.

Activists online said security forces used tear gas to disperse the crowds and carried out mass arrests.

An opposition spokesman told AFP news agency that a third person was killed in protests on Thursday (yesterday).

Reuters news agency meanwhile reports governments forces fired live rounds at thousands of people gathering to mourn one of the dead.

Protest have also spread to six other cities nationwide, and activists have announced fresh demonstrations beginning tomorrow, the 20th of January.

The government has confirmed 24 people have died, but human rights groups say the number could be far higher.

At least 816 people have been arrested so far in the unrest.
