Five demining experts killed in a weekend explosion in Yemen were from South Africa and several European countries, King Salman Humanitarian Aid and Relief Centre (KSRelief) in charge of the project said on Monday.
The KSRelief said two South Africans, a Croatian, a Bosnian and a Kosovan were killed on Sunday when a vehicle carrying mines to be destroyed exploded in the central province of Marib.
A British national was injured in the explosion, KSRelief said without naming the casualties.
The Houthi militias have been accused of the widespread and indiscriminate use of landmines.
Yemen is a signatory to the Mine Ban Treaty, an international pact which came into force in 1999 and aims to eliminate landmines and clear up vast tracts of affected land.
