SUEZ, Egypt, Jan 27 (Reuters) - Egyptians torched a police post in the eastern city of Suez early on Thursday morning over the killing of protesters in anti-government demonstrations earlier in the week, a witness said.

The Reuters witness said police fled the post before the protesters burned it using petrol bombs. Dozens more gathered in front of a second police post later in the morning demanding the release of their relatives who were detained in protests.

Demonstrations demanding the resignation of President Hosni Mubarak, in power since 1981, have raged since Tuesday across several cities, including Cairo and Suez. (Reporting by Yusri Mohamed, Writing by Edmund Blair)
