CAIRO (Reuters) - Egypt's President Abdel Fattah al-Sisi said on Tuesday that there would be severe regional consequences if Egypt's water supply was impacted by a giant hydropower dam being built by Ethiopia.

"I'm not threatening anyone here, our dialogue is always reasonable and rational," Sisi said in a response to a question about any risk to Egypt.

"I say once again no one can take a drop from Egypt's water and if it happens there will be inconceivable instability in the region."
