Why has drone attack at an Egyptian port raised security concerns?

A drone attack at Egypt's Damietta port has raised security concerns owing to its nearness to another major global chokepoint, the Suez Canal and Sumed pipeline. Amid blockades of Hormuz and Bab-el-Mandeb straits, Suez Canal remained a vital route for Saudi Arabian oil. If disrupted, passage through Red Sea would be cut, and ships would have to detour around Africa.
