LONDON, Sept 17 (Reuters) – British Prime Minister Boris Johnson agreed with German Chancellor Angela Merkel on Tuesday they needed to work with international partners to form a collective response to Saturday’s attacks on Saudi oil plants, his spokesman said.

The two leaders also agreed there was a need to de-escalate tensions in the region and were committed to a common approach on Iran, which has been blamed by U.S. President Donald Trump for the attack on Saudi oil facilities.
