British Prime Minister David Cameron and United States President Barack Obama discussed on Friday the British Parliament’s block on UK involvement in possible military action in Syria, the BBC reports.

The two men spoke by phone for 15 minutes, and the tone of the conversation was said to be friendly.

The prime minister reiterated that he still wanted to see a strong response to the suspected chemical weapons attack.

At the same time, he also explained the parliamentary process to the U.S. president, who said he understood Cameron’s predicament, according to the BBC.

On Thursday, British MPs voted to reject possible military action against the Assad regime in Syria to deter the use of chemical weapons. A government motion was defeated by 285 to 272.

Cameron said following the vote that it was clear Parliament does not want action and added that “the government will act accordingly.”

Despite the result of the vote, the U.S. said it would continue to seek a coalition for military intervention, while France said the vote did not change its resolve about the need to act.

U.S. Defense Secretary Chuck Hagel said the White House respected the British vote and that it was still seeking an “international coalition that will act together against Syria’s regime.

“We are continuing to consult with the British as with all of our allies. That consultation includes ways forward together on a response to this chemical weapons attack in Syria,” he said.

In their conversation Friday, Obama and Cameron agreed the U.S. and UK would work closely together on a wider response to the Syrian crisis and try to find a solution.

Also on Friday, U.S. Secretary of State John Kerry spoke about the chemical attack near Damascus last week, calling Assad “a thug and a murderer” and saying that at least 1,400 people, including 400 children, were killed in that attack.

Kerry said that U.S. intelligence had concluded that the Syrian regime was behind the attack and urged the world to take punitive action.

Obama later told reporters that he has not made a final decision about a military strike against Syria, but added he is considering a limited action in response to the chemical weapons attack.
