Ayman Mohyeldin was in a coffee shop joking with colleagues in Gaza City when the first Israeli bomb struck, smashing into a police station just a short distance from where they were sitting. The tremors from the explosion shook the café, but it took a few minutes for the reality to sink in – Gaza was under attack.

Since that moment 18 days ago, Mr Mohyeldin and his colleagues at al-Jazeera English, the satellite channel, have worked day and night, providing 24-hour coverage of the Israeli offensive in Gaza and the humanitarian crisis it has triggered.
