LONDON, April 12 (Reuters) - U.S. President Donald Trump and Britain's Prime Minister Theresa May agree on the need to find an international response to deter the use of chemical weapons in Syria, the British prime minister's office said on Thursday. May spoke with US President Trump Thursday night about the international response to Syria, and they "agreed that the Assad regime had established a pattern of dangerous behavior in relation to the use of chemical weapons," according to a Downing Street statement. "Cabinet agreed that the Assad regime has a track record of the use of chemical weapons and it is highly likely that the regime is responsible for Saturday's attack,” a statement from Downing Street said, using the same phrase it deployed following the Sergei Skripal poisoning last month. Cabinet agreed the Prime Minister should continue to work with allies in the United States and France to coordinate an international response.”

The British government issues a statement saying it is "highly likely" the Assad regime used chemical weapons on its own people, and that since such an action could not go unchallenged, Britain would work with United States and France to coordinate an international response, without specifying what measures the United Kingdom would take.
