Hello.

Please tell me if it is possible to say in English:
1)thousands of protesters "came out in (?)the streets". (meaning "took to the streets"; is the preposition "in" correct?)
2)The French foreign minister "conducted" a meeting with his British counterpart. (maybe, "held"?)
Thank you for all your help.

1. "came out in the streets" and "took to the streets" are both fine.

2. "conducted" and "held" are both fine.
