PRISTINA, Kosovo — Opposition lawmakers angry at Kosovo's recent deals with Serbia and Montenegro set off tear gas canisters Thursday in Parliament, forcing the suspension of the session.

Lawmakers left the chamber after witnesses said a tear gas canister was opened in the opposition seats, followed by one or two others. It was the second week in a row that tear gas had been used in Parliament in protests that began with the egging of Prime Minister Isa Mustafa last month.

The opposition, led by the Self-Determination party, said no more parliamentary sessions should be held and pledged to continue the protests.
