KAMPALA, Uganda – Hundreds of rescuers and volunteers dispersed through devastated neighborhoods in Equatorial Guinea’s largest city on Monday, looking for survivors a day after a series of massive explosions erupted in the Central African nation.

Television footage showed vans, taxis, vans and ambulances plying the port city of Bata, carrying people who had been injured in Sunday’s explosions. The explosions were triggered by poorly stored dynamite kept at a military base near the Atlantic coast, President Teodoro Obiang Nguema Mbasogo said on Sunday.

As of Monday, clinics were running out of beds, according to state media. The country’s health ministry said the number of people confirmed dead had risen to 98, with more than 600 hospitalized. Officials said they expected the death toll to rise.

The explosion drew comparisons with The massive explosion in Lebanon at the Port of Beirut in August, which killed 210 people and caused some $ 15 billion in property damage, and the 2002 explosion at an arms depot in Lagos, Nigeria, which killed more than 1,000 people

The disaster in Equatorial Guinea is a major test for Mr. Obiang, the world’s oldest president. On Monday, the main opposition party accused him of mismanaging the crisis, which it said exposed the poor state of the oil-rich country’s health system. The tiny country of 1.5 million people, home to Africa’s third-largest crude oil reserve, has been plagued by years of widespread corruption under Mr. Obiang, in power since 1979, when Jimmy Carter was President of the United States.
