The ICJ did not immediately respond to a request for comment.
Gambia has accused Myanmar of violating the 1948 Genocide Convention in a military campaign that expelled more than 730,000 Rohingya from the country.
It asked the ICJ to order “provisional measures” to prevent more harm, a first step in a legal case that is expected to go on for years.
Myanmar’s leader, Aung San Suu Kyi, travelled to The Hague last month to defend her country against the charges.
She denied that genocide was taking place and said the court has no jurisdiction to hear the case.
Aung San Suu Kyi, once championed in the West for her decades-long fight for democracy for Myanmar, said Myanmar did investigate and prosecute soldiers and officers accused of crimes.
She said that under those circumstances, the court should not intervene.
The Gambia lodged its lawsuit after winning the support of the Organisation for Islamic Cooperation (OIC), which has 57 member states. Only a state can file a case against another state at the ICJ.
The Gambia has said Myanmar cannot be trusted to bring alleged military perpetrators of crimes against the Rohingya to justice.
