At least 24 people were killed in a stampede at a beachside concert celebrating the end of Ramadan in Guinea's capital, the French news agency AFP reported.
A statement released by the president of Guinea declared a week of mourning after the deadly stampede, calling the incident a "tragic drama."
The French news agency AFP said the stampede Tuesday at a beach in Conakry's Ratoma neighborhood left 24 people dead.
The popular Guinean rap group Instinct Killers, among other artists, was playing at a celebration marking the end of the Ramadan holiday.
The presidential statement noted some deaths and injuries but did not give a death toll.
"While waiting for the results of an investigation, information from health and security authorities indicate deaths and several injuries," the Presidency said late Tuesday.
An investigation has been launched to determine what caused the tragedy. The official in charge of organizing such events was suspended, AFP reported.
