21down- Tips ignored, employ length of wire for fishing in the river (5) s?i?e

18down- Brown maintains here to be explosive (7)
T?H?R?N . Looks like Teheran but where is the anagram indicator for Here?

[another-view]

explosive?

TAN = brown but I don't see where the definition is for TEHERAN.

[mazie]

Seine ?

[Mampara]

Thank you. I saw the TAN (brown) but it is the EHER and the definition- explosive that is confusing.

[Mampara]

Thanks but why Seine - other than being a river?

[squarebear]

Yes I would take "explosive" to be the anagram indicator. I don't see the definition.

21d use line minus first letters (tips ignored)

[Mampara]

Thank you Sedge & square bear.

(U)se (L) ine = Seine

[mazie]

sorry i didnt get back to you Mampara (been working)
Just the river bit really! I'm a cryptic novice!

[ventpeg]

the definition is the word 'here' ie Teheran (a place)

Seine is also a large fishing net made to hang vertically in the water by weights at the lower edge and floats at the top. To seine is to fish in such a way.
