NEW DELHI: Amid war-like conditions in Yemen's Aden, the Navy on Saturday pressed into action INS Mumbai, a guided-missile destroyer, to evacuate the second batch of Indians from the port city.The warship placed itself just outside Aden harbour as part of "Operation Raahat" as heavy firing was reported in Aden where the Saudi-led coalition is fighting Houthi rebels who are making a bid for the city.Indian authorities have hired small crafts which are being used to move 30-35 Indians at one time from the port to INS Mumbai , the Navy said. The warship could not dock at the city port due to heavy shelling.While the exact number of Indians stranded there is not known, defence sources put it over 200."Absolute tough environment at Aden ...

Singh has come back to Djibouti on Saturday.Sources said though security situation was becoming more precarious in Sanaa due to increasing hold of al-Qaida terrorists, India has been given slots to carry out air sorties to take out its citizens from the city."Maximum slots to carry out air sorties have been given to India. We were given two slots yesterday and two slots today. We hope to continue the evacuation from Saana."Supporters of the Houthi rebels demonstrate against the Saudi-led air strikes on Yemen, in Sanaa.
