In June 2023, IOM Yemen DTM recorded 10,800 migrants entering Yemen, a decrease of six per cent since last month (11,463 migrants in May 2023). There was no major change (+1%) in the number of migrants arriving through Yemen's Lahj coast (from 8,711 in May to 8,789). However, there was a decrease (-27%) in the number of migrants arriving through Shabwah's coast (from 2,748 in May to 2,008 in June) due to changes in the weather conditions, namely high tides and windy weather. DTM recorded conflict induced movements as the reason for 15 per cent of all incoming movements in June 2023. All conflict induced travel was recorded in Shabwah coming from Bari, Somalia (32% children, 12% women, and 56% men).

Due to the deteriorating humanitarian crisis in Yemen and the challenges in moving towards KSA, many migrants opted to return to the Horn of Africa. DTM teams in Djibouti recorded that during June 2023, a total of 547 migrants (532 male and 15 female) took the risky return by boat from Yemen to travel home. Meanwhile, DTM observed a significant decrease in Yemeni returnees (-58%) compared to last month (5,466 in May to 2,322 in June) since Saudi authorities have primarily focused on pilgrims (Al Haj) and hence temporarily delayed deportation during this period.

Between 1 January and 30 June 2023, DTM recorded 77,130 migrants and 27,078 Yemeni migrant returnees to Yemen.

IOM DTM received further information from border officials during June 2023 regarding the deportation of 80 migrants (50 Ethiopian, 29 Yemeni, and 1 Somali nationals) from Oman into Hawf district of Al Maharah governorate. These migrants had travelled through Yemen to Oman but were deported back into Yemen by Omani authorities.
