Indian Navy ship INS Mumbai in the Gulf of Aden, off Yemen
About 800 Indians have been evacuated from strife-torn Yemen where the situation has deteriorated significantly due to escalation in fighting between warring groups.
With Saturday's 800 evacuations, India has so far taken out over 1,800 of its citizens from the country.
Minister of State for External Affairs VK Singh, who was overseeing the massive evacuation operation from Djibouti, had also gone to Sana'a, the capital of Yemen from where Air India rescued Indian nationals after getting permission to land.
Mr Singh has gone back to Djibouti on Saturday.
Meanwhile, Navy ship INS Mumbai sent to evacuate Indians from Aden could not dock at the city port due to heavy shelling and small boats were used to ferry the people to the ship.
"There is heavy shelling in Aden. The ship is anchored 5-6 kilometres off the coast. Indian nationals are being taken by boat to board the ship there," External Affairs Minister Sushma Swaraj said.
Official sources said the evacuation operation was going on despite the deteriorating situation across Yemen.
"We hope to complete the evacuation operation in the next few days," they said.
The sources said though security situation was becoming more precarious in Sana'a due to increasing hold of al-Qaeda, 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 on Friday and two slots on Saturday. We hope to continue the evacuation from Sana'a."
They sought to allay fears of kidnapping of Indians in Yemen, asserting that the situation was not like that in Iraq.
The sources said Indian Navy ship Tarkash and two other commercial ships are also available for evacuation of Indians from port cities including from Al-Hudaydah.
They said India had rescued two Nepalese and three nationals each of Bangladeshi and Pakistan also from Al-Hudaydah city two days ago.
External Affairs Ministry Spokesperson Syed Akbaruddin said over 300 Indians have been brought back from Sana'a and had reached Djibouti enroute to India.
"Two Air India flights out of Sana'a land in Djibouti on Saturday with 325 people on board," he tweeted.
He also tweeted that about 800 Indians who were evacuated today.
The sources said situation in Sana'a was serious as militants have stepped up their offensive and particularly due to movement of heavy artillery and missiles during nights.
"The security situation is deteriorating every day," sources said.
A no-fly zone enforced in Yemeni airspace by international coalition has made it difficult to evacuate Indians by air, they said, adding India has been requesting Saudi Arabia to allow aerial sorties to Sana'a on a daily basis.
The sources said the number of Indians across Yemen was around 5,000 out of which 1,000 were women married to Yemeni nationals. The number of Indians in Sana'a would be around 3,000 while around 554 were in Aden and 298 were in offshore oil fields.
Talking about air sorties from Sana'a, the sources said air operations at times become difficult as clearance given by authorities in the Yemeni city does not reach those in Djibouti.
So far, a maximum of 337 people hailing from Kerala followed by 246 from Maharashtra have been brought back. A total of 86 people from Andhra Pradesh and Telangana, 15 from Bihar, 48 from Delhi, two from Goa and 30 from Gujarat, one from Jammu and Kashmir and 34 from Karnataka have also been brought back.
Among those who were evacuated include one each from Madhya Pradesh and Odisha, four from Rajasthan, 85 from Tamil Nadu, 30 from Uttar Pradesh, 42 from West Bengal and 16 from other states, as per official details.
