70th session of UN General Assembly: LIVE UPDATES

The UK will continue to engage Islamic State targets for "as long as it takes", British Foreign Secretary, Philip Hammond, told the United Nations, urging unity in order to "crush" the jihadists.

“We share a responsibility to act to end the bloody civil war and create an inclusive political process, and to work together to crush ISIL and banish its twisted ideology from the face of the earth.”

Russian Foreign Minister Sergei Lavrov attended a meeting with his counterparts from BRICS nations on the sidelines of the UN General Assembly in New York.

Yemen's exiled president Abd-Rabbu Mansour Hadi blamed Iran for supporting the Houthi militia which are battling the Saudi-led coalition.

"We find ourselves mixed in this battle, this fight for the country and the legitimacy of the state to ensure that the country not fall into the hands of Iran, which would like to see the destruction of the country," Hadi told the General Assembly.

Despite massive devastation and numerous civilian casualties caused by Saudi coalition bombardment and troops on the ground, Hadi blamed the Houthis for the humanitarian crisis.

"You are aware of the human tragedy of our people, and this is due to the blockade imposed by the militias," he said.

President Ellen Johnson-Sirleaf of Liberia said that the world needs to find way to aid the healthcare system in Africa.

“Weak public health systems in individual countries threaten global health and well-being,” said Johnson-Sirleaf. “It is not beyond this body to find answers and respond, and we know that we must.”

Speaking about Ebola, the Liberian president thanked the world community for offering aid.

“As we ponder, in Liberia, Guinea and Sierra Leone, three countries worst-hit by the deadly Ebola Virus Disease, we bear witness to the foundational creed of the United Nations – that we can always find it within our humanity to respond even to unknown enemies to our collective progress,” she declared. “Accordingly, we remain grateful to all of you for the outpouring of support and assistance as we faced down the deadly Ebola Virus Disease, the greatest modern threat to global public health.”

Venezuelan President Nicolas Maduro condemned the UN's response to the civil war in Syria, as well as US-led invasions in Afghanistan, Iraq, and Libya, which he said had "destroyed" those countries.

"We have sought to make our voice heard," he said. "We have recognized the tragic mistakes that have been made in invading and bombing countries and peoples, brotherly peoples in the world. The four wars that have been waged destroyed important countries here."

"The strategic failure of these four wars relates to what is being done in the Security Council. The inability of the United Nations to act," he added.
