Prime Ministers of Albania
Albanian police said on Monday they are working with the prosecutors to find out what happened at an opposition Democratic Party rally on Saturday in Tirana, after which about 140 people complained of suffering mysterious ailments.
Problems included red, swollen eyes, skin irritations, vomiting and difficulties with breathing.
Ilir Meta, leader of Albania's junior ruling party, the Socialist Movement for Integration, LSI, was voted in as President of Albania on Friday amid an opposition boycott.
Meta received 87 votes in favour and two against in the 140-seat assembly, becoming the seventh President of Albania since the Stalinist Communist regime collapsed in 1990.
Albania's Central Election Commission on Thursday refused to postpone a deadline for parties and coalitions to register for upcoming general election in June, leaving the ruling parties heading into the polls alone.
The general elections are therefore set to go ahead without the presence of opposition parties, which refused to register for the vote.
The Albanian parliament failed to elect a new president on Wednesday after Prime Minister Edi Rama's governing Socialists decided not to offer a candidate in the first round of voting.
