Prime Minister Sheikh Hasina reached Budapest from Turkmenistan yesterday evening after a Biman plane carrying her had to make an emergency landing at the Ashgabat International Airport.

The VVIP flight of the national flag carrier that left Shahjalal International Airport at 9:14am was forced to make the emergency landing at the Ashgabat International Airport in Turkmenistan at 2:15pm (BST) due to a “drop in oil pressure” in engine number-1, Biman Managing Director & CEO AM Mosaddique Ahmed, told The Daily Star.

After having the problem fixed, the Boeing 777-300ER left Ashgabat Airport at 6:37pm (BST) for Hungary, said Shakil Meraj, general manager (public relation department) of Biman, in a press release.

"The flight reached Budapest at 11:05pm [BST]," he said, adding that all passengers of the flight were safe.

Shakil also said Biman would form an enquiry committee to investigate the incident. He, however, could not give details in this regard.

When the PM's plane was being fixed, a London-bound schedule flight of Biman was sent to Ashgabat Airport to be a backup for the premier and her entourage, the Biman release added.

In June, a flight of Biman carrying the PM had to circle over Dhaka for around 20 minutes before landing at the Shahjalal International Airport. Fragments of titanium blades of an aircraft engine got scattered on the lone runway of the airport after it had aborted take-off.

During her brief stay at the Ashgabat Airport, deputy prime minister and foreign minister of Turkmenistan, among others, called on Hasina, State Minister for Foreign Affairs M Shahriar Alam said in a Facebook post.

From Bangladesh, Hasina left for Budapest on a four-day visit at the invitation of Hungarian President Janos Ader to attend the Budapest Water Summit 2016 beginning today.

She was leading a 90-member delegation which includes three cabinet ministers -- LGRD, Water Resources and Foreign Affairs -- 12 senior officials from the Prime Minister's Office, nine officials from the foreign ministry, four high officials from different ministries, eight security personnel, 15 in the media team, and 39 businessmen.
