India is executing one of the most challenging rescue operations in strife-torn Yemen , pulling out its own and citizens from at least 26 other countries.On Monday , India evacuated over 1,000 (574 from Sana'a by air and 479 from Al Hodeida by sea) executing a sophisticated air-sea operation showcasing its maritime power. Until now, India has evacuated over 3,500 of its nationals and 225 citizens of at least 26 countries in a rare gesture.Maldives has joined 25 countries requesting India for help. The fact that such requests continue to come is being seen as a vote of confidence in Indian capability. India has evacuated nationals of almost all its neighbours (Pakistan has pulled out 11 Indians) and taken in US, UK, German and Malaysian nationals among others.India's decision to make Djibouti the operation's hub served the authorities well.People are being taken out of Aden, Sana'a, Al Hodeida and Al Mulala , ferried to Djibouti and thence by Air India planes and IAF C-17 Globemaster aircraft.

The ex-Army chief is the right man in the right place. He has taken charge, studied the complexities in ways civilian ministers wouldn't have, commanded and received support from "faujis" on the ground. He spent a day and night in war torn Sana'a overseeing logis tics before going to Djibouti He greeted evacuees: "You are now in Indian care."Until this week, India has operated 10 flights out of Sana'a, from an airport that's partly bombed out.
