Two people have been killed in an explosion in a stadium in Madagascar which authorities have described as a terrorist attack.
Dozens of people were injured in the incident in the Mahamasina stadium, where people had gathered to celebrate the country's 1960 independence from France.
The Madagascar Tribune reports that Madagascar's president, Hery Rajaonarimampianina, has visited some of the injured in hospital and expressed his condolences to the families of the dead.
The government has promised tough action against those it accuses of using violence for "political reasons".
Mr Rajaonarimampianina's election in 2014 came after five years during which Madagascar was led by a regime that seized power in a coup.
Despite hopes that his election would bring stability, the president has faced an impeachment attempt in the National Assembly.
Some 84 people were wounded in the attack, reported L'Express de Madagascar.
The Madagascar Tribune described the attack as a "nightmare" and, in an editorial, questioned how an assailant could have smuggled a grenade into the stadium. It noted that emergency services were not widely deployed in the area.
Security commanders had addressed the media last week about plans to secure the stadium amid rumours that the celebration might be targeted.
