Saudi warplanes continue to pound the Yemeni capital city of Sanaa at an increased rate on Thursday, while operations on the ground appear to have shifted southwest, with pro-Saudi forces attacking coastal areas held by the Shi’ite Houthi movement.

Reports out of the Khoukha District, on the Red Sea coast of Yemen, say that pro-Saudi forces have more or less entirely captured the area, which includes a town and a small fishing port. At least 25 were killed in the fighting.

The disstrict itself of is limited value, but the push is in keeping with Saudi-led efforts to conquer as much of the Yemeni coast as possible, to ensure that shipments of food and medicine into the country are done more or less exclusively under their control.

Fishing ports notwithstanding, the Houthi movement only has a single port, at Hodeidah, which would need food and medicine imports for 15 million people in northern Yemen. A Saudi blockade, however, allows a tiny fraction of that in.
