Burj Khalifa lit up in Lebanese flag colours in solidarity with its people.

His Highness Sheikh Mohammed Bin Rashid Al Maktoum, Vice President and Prime Minister of UAE and Ruler of Dubai, offered condolences to the people of Lebanon after the horrific port explosions.

Sheikh Mohammed said, “Our condolences to our beloved people in Lebanon... Oh God, have mercy on those... Oh God, give the people of Lebanon patience and solace...”

His Highness Sheikh Mohamed Bin Zayed Al Nahyan, said, “Our thoughts and prayers are with our Lebanese brothers and sisters during these trying times. We pray that God grants you patience and solace. God bless Lebanon and the Lebanese people.”

Dr. Anwar Bin Mohammed Gargash, Minister of State for Foreign Affairs, said on Twitter, “Our hearts are with Beirut and its people.Our prayers during these difficult hours are that the God to protect the brotherly Lebanon and the Lebanese people, and to heal their wounds, and keep their homes safe from sorrows and pain."

The two enormous explosions rocked Beirut's port on Tuesday, killing at least 27 people and wounding thousands, shaking distant buildings and leaving the Lebanese capital in fear and chaos.

The deafening second blast sent an enormous orange fireball into the sky, flattened the harbourside and sent a tornado-like shockwave ripping through the city, shattering windows kilometres away.

Bloodied casualties stumbled among debris and burning buildings across central Beirut as Health Minister Hamad Hassan reported an initial estimated toll of 73 dead and 3,700 injured, calling it "a disaster in every sense of the word".
