Two Turkish nationals suffered minor injuries in a blast that rocked Beirut, the Turkish Foreign Ministry said late Tuesday.

The ministry said their health conditions are being closely monitored and extended condolences to the people of Lebanon.

"It was learned with deep sorrow that many Lebanese brothers died or were injured in the explosions at Beirut Harbor today," it said.

A fire caused a massive blast Tuesday at a warehouse storing explosives at the Port of Beirut. The exact cause of the blast is unknown.
