The attack was a crime against humanity, said Davutoglu following his meeting with British Foreign Secretary William Hague.

- "International response to Syrian crisis was not on time"
Davotoglu criticized the international community, particularly the UN, for not responding to the crisis in Syria on time.
"The international community set the ground for the Syrian regime to increase violence by not reacting on time, " said Davutoglu.
- "Egypt should not descend into chaos"
Davutoglu said Egypt is a great country with a rooted history and should not descend into chaos.
Since Egypt's first democratically elected President Mohamed Morsi was ousted in a July 3 military coup, there have been massacres in the country, said Davutoglu, calling on the international community to take steps to put an an end to the crisis.
"We belive that any political solution to the crisis in Egypt can be found only if Morsi is involved in this process," he said. " We will continue to exert efforts in this direction."
"Turkey always has principled policies towards Syria and Egypt. We have wished the same things for both of the two countries, and have responded to violence in both Syria and Egypt in the same way," he said.
He reiterated that Turkey would continue to support the Syrian and Egyptian people.
Davutoglu said he had also held a phone conversation with US Secretary of State John Kerry over the crisis in Syria and Egypt.
