LONDON, Jan 12 (Reuters) - At least four oil tankers have diverted course from the Red Sea since overnight strikes by the U.S. and Britain on Houthi targets in Yemen, shipping data from LSEG and Kpler showed.

The attacks were carried out from the air and sea in response to the Iranian-backed Houthi militia's attacks on ships in the Red Sea, in what is becoming a regional escalation of the Israel-Hamas war in Gaza.
