The Nigerian Maritime Administration and Safety Agency (NIMASA) said the spill which occurred on Saturday at the Bonny terminal has reached shoreline and that it was actively monitoring the situation.
NIMASA added that it was also working with Shell Petroleum Development Company (SPDC) and other stakeholders to assess the extent of the spill and follow-up actions.
The maritime agency said SPDC has shut down the affected pipeline and deployed containment booms to protect neighbouring communities.
