Two Bahraini soliders taking part in the Arab military coalition in Yemen died on Tuesday inside Saudi Arabia’s southern borders, the tiny Gulf kingdom’s state news agency reported on Tuesday.

The two soldiers, Captain Ahmed Mohammed Ameen and Captain Mubarak Sa’ad Al-Rumaihi, died during an “incident” on border with Yemen. Saudi shares a 1,800 kilometer frontier with its war-wracked neighbour.

The two were “performing their sacred national duty” to “defend legitimacy in Yemen,” the statement said.

The statement gave no further details.

Since late March, the Saudi-led coalition has bombed Iranian-backed Houthi militias and forces allied to deposed leader Ali Abdullah Saleh, in a bid to put the government of internationally recognized President Abdrabbu Mansour Hadi back in power.
