DAKAR, Senegal — At least 30 bodies were found on a boat drifting off the coast of Senegal’s capital, the military said Monday, as the number of migrants leaving West Africa increases.

The navy was informed of the vessel’s presence on Sunday evening and sent out a boat patrol to the area, 70 kilometers (38 nautical miles) from Dakar, Ibrahima Sow, spokesperson for Senegal’s military said in a statement.

“So far, 30 bodies have been counted,” Sow said.

The advanced state of decomposition of the bodies is making the identification process very difficult, the military said, adding that investigations will provide more information on the death toll and the boat’s origin.

Earlier this month, a boat carrying 89 people on board capsized off the coast of Senegal. At least 37 people died, according to Senegalese authorities.

Many of the migrants leaving West Africa through Senegal flee conflict, poverty and a lack of jobs. Most head to the Canary Islands, a Spanish archipelago off the coast of West Africa, which is used as a stepping stone to continental Europe.

Since the beginning of the year, more than 22,300 people have landed on the Canary Islands, 126% more than the same period last year, according to statistics released by Spain’s Interior Ministry.
