At least 24 people have died in a stampede at a beach concert in Conakry, the capital of Guinea, to mark the end of the Muslim holy month of Ramadan.

The president's office has declared a week of national mourning after what it called a "tragic drama" at a concert by the Guinean rap group Instinct Killers.

Dozens of people were injured, said police sources quoted by AFP.

The concert took place on Tuesday evening on a beach in Ratoma, a northern suburb of Conakry.

The authorities were "shocked by the tragic drama caused by mass movements at a cultural event," said a statement from the president's office.

Hospital sources said there were 13 girls among the dead.
