Hello. I'll appreciate it if you answer my questions:

1)is it possible to say "Thousands of Egyptians conducted a meeting in Cairo" (meaning "held a protest")or is the word "meeting" something like "discussion"?
2)is it possible to use "confine" in the structure "a confined man" (meaning "a jailed man")?
Thank you very much.

1) They might have held a meeting. But considering the news, a more accurate sentence would be: "Thousands of Egyptians protested in Cairo."

2) A jailed man is more exact. Confined could mean he was bed-ridden or in a hospital.
