The Palestinian-British reconstructive surgeon, who last year spent the first 43 days of the war treating patients in Gaza, see parallels between the two conflicts.
Hamas's attack on Israel resulted in the deaths of 1,205 people, most of them civilians, according to an AFP tally based on official Israeli figures.

The United Nations has said the figures are reliable.
