The UK's UN ambassador "strongly" agreed with Turkish President Recep Tayyip Erdogan on Tuesday amid a mounting offensive on northwestern Syria's Idlib province.

Axar.az reports citing United Nations.

“We strongly agree with President Erdogan,” Karen Pierce told the UN Security Council citing an op-ed penned by Erdogan.

Erdogan on Monday said in the Wall Street Journal: “All members of the international community must understand their responsibilities as the assault on Idlib looms. The consequences of inaction are immense.”

“A regime assault [in Idlib] would also create serious humanitarian and security risks for Turkey, the rest of Europe and beyond,” he added.

He also noted Turkey's role in protecting the Syrian people, as it hosts the largest number of refugees in the world at 3.5 million.

"Turkey has a plan, Madam President, in Idlib and it does involve reaching an agreement with the Syrian opposition whereby the regime refrains from attacking them while they combat terrorism," she said referring to Nikki Haley, the U.S.'s UN envoy and council president.

She alleged Moscow, Tehran and Damascus are not interested in pursuing a political solution to the Syrian crisis, saying “Turkey learned this lesson last week” during trilateral talks in the Iranian capital.

The UN warned Monday at least 30,000 residents in Idlib have been displaced in the first nine days this month amid the Russian and regime air campaign there.
