At least 33 people were killed in a stampede following a beach concert in Guinea's capital of Conakry, local media reported Wednesday.

The tragedy occurred Tuesday when the crowd were leaving through a narrow gate after the concert, which was organized to celebrate the end of Ramadan.

Some people fell onto the ground and were trampled on, according to the reports.

Thousands of people, mostly children and youths, went to the concert to watch the performance of local popular rap groups.

The Guinean government called the incident a "tragic drama" and sacked an official in charge of the entertainment agency.

Guinean President Alpha Conde has announced a week of national mourning for the victims.
